  • Meta tag depending of selected language and title

    - by lena
    Hi, I'm aware about Google ignore most of the time, meta tag and use content. (This is not the point here) I'm working on an existing web site, not created by me. I need a quick solution, I guess with variables. The website construction: (no known template system) index.html which is presentation page with language selection index.php which embeding menu, content, footer several content pages that are embedded by index.php What I need to do only for those 2 pages welcome_en.html and welcome_fr.html (these pages are embedded so no header possible on these page) to have different page title (browser title) and different META tag. Any solution is welcome Thanks extra information Language detection on index.php: <?php $lang = $_GET['lang']; $page = $_GET['page']; if ($_GET['page'] == "" || !$_GET['page']) { $page = "welcome"; } if ($_GET['lang'] == "" || !$_GET['lang']) { $lang = "_fr"; } ? <td><img src="images/ban02<?php echo "$lang" ?>.jpg" width="531" height="60" <?php if ($_GET['lang'] == "_fr" || $_GET['lang'] == "" || !$_GET['lang']) { echo "alt='text'";} else if ($_GET['lang'] == "_en") {echo "alt='text'"; } ?>></td> for the embeded menu, footer ect like this one <?php include "menu.php"; ?> for the embedded content <?php //echo "$page$lang.html"; $lang = preg_replace('/[^a-z0-9_ ]/i', '', $_GET['lang']); $page = preg_replace('/[^a-z0-9_ ]/i', '', $_GET['page']); include $page . $lang . ".html"; ?>

  • Is it possible to guarantee a unique id for multiple items using the same id variable at a point in

    - by Scarface
    First of all, do not be overwhelmed by the long code, I just put it for reference...I have a function that preg_replaces content and puts it in a jquery dialog box with a matching open-link. For example, if there is a paragraph with two matches, they will be put inside two divs, and a jquery dialog function will be echoed twice; one for each div. While this works for one match, if there are multiple matches, it does not. I am not sure how to distribute unique ids at a point in time for each of the divs and matching dialog open-scripts. Keep in mind, I removed the preg replace function since it kind of complicates the problem. If anyone has any ideas, they will be greatly appreciated. <?php $id=uniqid(); $id2=uniqid(); echo "<div id=\"$id2\"> </div>"; ?> $.ui.dialog.defaults.bgiframe = true; $(function() { $("<?php echo"#$id2"; ?>").dialog({hide: 'clip', modal: true ,width: 600,height: 350,position: 'center', show: 'clip',stack: true,title: 'title', minHeight: 25, minWidth: 100, autoOpen: false}); $('<?php echo"#$id"; ?>').click(function() { $('<?php echo"#$id2"; ?>').dialog('open'); }) .hover( function(){ $(this).addClass("ui-state-hover"); }, function(){ $(this).removeClass("ui-state-hover"); } ).mousedown(function(){ $(this).addClass("ui-state-active"); }) .mouseup(function(){ $(this).removeClass("ui-state-active"); }); });

  • Retrieving ids from MySQL query

    - by Matt Maclennan
    I am having trouble accessing the "model_id" and "brand_id" from the foreach loop that I am using. They are the right field names, because I have echoed them successfully, and I have also "var_dumped" the array, and the IDs are there. It is just a case of implementing the relevant links on each list section. Below is the code I have. <? $output = mysqli_query("SELECT * FROM bikes, bikeTypes WHERE bikes.model_id = bikeTypes.model_id"); $result = array(); while($row = mysqli_fetch_array($output)) { $result[$row['model']][] = $row; } foreach ($result as $category => $values) { echo "<li><a href='test.php?id=" . $row['model_id'] . "'>".$category.'</a><ul>'; foreach ($values as $value) { echo "<li><a href='details.php?id=" . $row['brand_id'] . "'>" . $value['bikeName'] . "</a></li>"; } echo '</ul>'; echo '</li>'; } ?>

  • Need Associated ID Added to a While Loop (php)

    - by user319361
    Been trying to get my head around while loops for the last few days but the code seems very inefficient for what Im trying to achieve. I'm assuming I'm overcomplicating this though nothing I've tried seems to work. Each topic in my forum can have related topic IDs stored in a seperate table. A post ID is also stored in this table, as that specific post references why they are considered related. DB Table contains only: topic_id, related_id, post_id // Get related IDs and post IDs for current topic being viewed $result = $db->query('SELECT related_id, post_id FROM related_topics WHERE topic_id='.$id.''); // If related topics found, put both of the IDs into arrays if ($db->num_rows($result)) { while($cur_related = mysql_fetch_array($result)){ $reltopicarray[] = $cur_related['related_id']; $relpost[] = $cur_related['post_id']; } // If the first array isnt empty, get some additional info about each related ID from another table if(!empty($reltopicarray)) { $pieces = $reltopicarray; $glued = "\"".implode('", "', $pieces)."\""; $fetchtopics = $db->query('SELECT id, subject, author, image, etc FROM topics WHERE id IN('.$glued.')'); } // Print each related topic while($related = mysql_fetch_array($fetchtopics)){ ?> <a href="view.php?id=<?php echo $related['id']; ?>"><?php echo $related['subject']; ?></a> by <?php echo $related['author']; ?> // Id like to show the Post ID below (from the array in the first while loop) // The below link doesnt work as Im outside the while loop by this point. <br /><a href="view.php?post_id=<?php echo $cur_related['post_id']; ?>">View Relationship</a> <?php } ?> The above currently works, however I'm trying to also display the post_id link below each related topic link, as shown above. Would be greatful if someone can lend a hand. Thanks :)

  • Trailing comments after variable assignment subvert comparison

    - by nobar
    In GNU make, trailing comments appended to variable assignments prevent subsequent comparison (via ifeq) from working correctly. Here's the Makefile... A = a B = b ## trailing comment C = c RESULT := ifeq "$(A)" "a" RESULT += a endif ifeq "$(B)" "b" RESULT += b endif ifeq "$(C)" "c" RESULT += c endif rule: @echo RESULT=\"$(RESULT)\" @echo A=\"$(A)\" @echo B=\"$(B)\" @echo C=\"$(C)\" Here's the output... $ make RESULT=" a c" A="a" B="b " C="c" As you can see from the displayed value of RESULT, the ifeq was affected by the presence of the comment in the assignment of B. Echoing the variable B, shows that the problem is not the comment, but the intervening space. The obvious solution is to explicitly strip the whitespace prior to comparison like so... ifeq "$(strip $(B))" "b" RESULT += b endif However this seems error prone. Since the strip operation is not needed unless/until a comment is used, you can leave out the strip and everything will initially work just fine -- so chances are you won't always remember to add the strip. Later, if someone adds a comment when setting the variable, the Makefile no longer works as expected. Note: There is a closely related issue, as demonstrated in this question, that trailing whitespace can break string compares even if there is no comment. Question: Is there a more fool-proof way to deal with this issue?

  • accessing private variable from member function in PHP

    - by Carson Myers
    I have derived a class from Exception, basically like so: class MyException extends Exception { private $_type; public function type() { return $this->_type; //line 74 } public function __toString() { include "sometemplate.php"; return ""; } } Then, I derived from MyException like so: class SpecialException extends MyException { private $_type = "superspecial"; } If I throw new SpecialException("bla") from a function, catch it, and go echo $e, then the __toString function should load a template, display that, and then not actually return anything to echo. This is basically what's in the template file <div class="<?php echo $this->type(); ?>class"> <p> <?php echo $this->message; ?> </p> </div> in my mind, this should definitely work. However, I get the following error when an exception is thrown and I try to display it: Fatal error: Cannot access private property SpecialException::$_type in C:\path\to\exceptions.php on line 74 Can anyone explain why I am breaking the rules here? Am I doing something horribly witty with this code? Is there a much more idiomatic way to handle this situation? The point of the $_type variable is (as shown) that I want a different div class to be used depending on the type of exception caught.

  • can I add properties to a typo3 extbase domain model object?

    - by The Newbie Qs
    I want to store a username in a coupon object, each coupon object already has the uid of the user who created it. I can loop over the coupon objects and read the associated usernames from fe_users but how then will I save those usernames into the coupons so when they are passed to the template the usernames can be read like so coupon.username, or in some other easy way so each username will appear on the page with the right coupon as they are all printed out in a table? If I was doing basic php instead of typo3 i would just define a query but what is the typo3 v4.5 way? My code so far - which dies on the line where I try to assign the new property --creatorname -- to the $coup object. public function listAction() { $coupons = $this->couponRepository->findAll(); // @var Tx_Extbase_Domain_Repository_FrontendUserRepository $userRepository */ $userRepository = $this->objectManager->get("Tx_Extbase_Domain_Repository_FrontendUserRepository"); foreach ($coupons as $coup) { echo '<br />test '.$coup->getCreator(); echo '<br />count = '.$userRepository->countAll().'<br />'; $newObject = $userRepository->findByUid( intval($coup->getCreator())); //var_dump($newObject); var_dump($coup); echo '<br />getUsername '.$newObject->getUsername() ; $coup['creatorname'] = $newObject->getUsername(); echo '<br />creatorname '.$coup['creatorname'] ; } $this->view->assign('coupons', $coupons); }

  • "for" loop inside another "for" loop

    - by jnkrois
    Hello everybody. I have quick question, and I'm sure some of you guys will be able to point out what I'm doing wrong. Basically, I want to create a table with (calendar), with the months and days of an entire year, and Im using php to do it, my code is doing something weird. What happens is that January is empty and the days for January are being put in february. My code so far is as follows: $months = 12; $monthsOfTheyear = array("Januany","February","March","April","May","June","July","August","September","October","November","December"); $currentMonth = date("n"); $currentYear = date("Y"); $daysOfTheMonth = cal_days_in_month(CAL_GREGORIAN, $currentMonth, $currentYear); for($i = 0; $i < $months; $i++){ echo " <tbody class='month'>"; echo " <tr> <td colspan='".$daysOfTheMonth."'> ".$monthsOfTheyear[$i]." </td> </tr> <tr> "; $daysOfEachMonth = cal_days_in_month(CAL_GREGORIAN, $i, $currentYear); for($d = 1; $d <= $daysOfEachMonth; $d++){ echo " <td> ".$d." </td> "; } echo " </tr> </tbody"; } I'm obviously doing something wrong, but I've been staring at the monitor for about an hour trying to figure it out. I'd appreciate any advice. Thanks

  • PHP5 getrusage() returning incorrect information?

    - by Andrew
    I'm trying to determine CPU usage of my PHP scripts. I just found this article which details how to find system and user CPU usage time (Section 4). However, when I tried out the examples, I received completely different results. The first example: sleep(3); $data = getrusage(); echo "User time: ". ($data['ru_utime.tv_sec'] + $data['ru_utime.tv_usec'] / 1000000); echo "System time: ". ($data['ru_stime.tv_sec'] + $data['ru_stime.tv_usec'] / 1000000); Results in: User time: 29.53 System time: 2.71 Example 2: for($i=0;$i<10000000;$i++) { } // Same echo statements Results: User time: 16.69 System time: 2.1 Example 3: $start = microtime(true); while(microtime(true) - $start < 3) { } // Same echo statements Results: User time: 34.94 System time: 3.14 Obviously, none of the information is correct except maybe the system time in the third example.

Here is my code: function decryptPassword($pw, $salt){ $hash = hash('sha256', $salt . hash('sha256', $pw)); return $hash; } function encryptPassword($pw){ $hash = hash('sha256', $pw); $salt = substr(md5(uniqid(rand(), true)), 0, 3); $hash = hash('sha265', $salt . $hash); return array( 'salt' => $salt, 'hash' => $hash ); } And here is my testing code: $pw = $_GET['pw']; $enc = encryptPassword($pw); $hash = $enc['hash']; $salt = $enc['salt']; echo 'Pass: ' . $pw . '<br />'; echo 'Hash: ' . $hash . '<br />'; echo 'Salt: ' . $salt . '<br />'; echo 'Decrypt: ' . decryptPassword($hash, $salt); Now, the output of this should be pretty obvious, but unfortunately, the $hash variable always comes out empty! I'm trying to figure out what the problem could be, and my only guess would be the second $hash assignment line in the encryptPassword(..) function. After a little testing, I've determined that the first assignment works smoothly, but the second does not. Any suggestions? Thanks SO!

  • How do I delete folders in bash after successful copy (Mac OSX)?

    - by cohortq
    Hello! I recently created my first bash script, and I am having problems perfecting it's operation. I am trying to copy certain folders from one local drive, to a network drive. I am having the problem of deleting folders once they are copied over, well and also really verifying that they were copied over). Is there a better way to try to delete folders after rsync is done copying? I was trying to exclude the live tv buffer folder, but really, I can blow it away without consequence if need be. Any help would be great! thanks! #!/bin/bash network="CBS" useracct="tvcapture" thedate=$(date "+%m%d%Y") folderToBeMoved="/users/$useracct/Documents" newfoldername="/Volumes/Media/TV/$network/$thedate" ECHO "Network is $network" ECHO "date is $thedate" ECHO "source is $folderToBeMoved" ECHO "dest is $newfoldername" mkdir $newfoldername rsync -av $folderToBeMoved/"EyeTV Archive"/*.eyetv $newfoldername --exclude="Live TV Buffer.eyetv" # this fails when there is more than one *.eyetv folder if [ -d $newfoldername/*.eyetv ]; then #this deletes the contents of the directories find $folderToBeMoved/"EyeTV Archive"/*.eyetv \( ! -path $folderToBeMoved/"EyeTV Archive"/"Live TV Buffer.eyetv" \) -delete #remove empty directory find $folderToBeMoved/"EyeTV Archive"/*.eyetv -type d -exec rmdir {} \; fi

  • How to take html markup from a string and escape it to work within a script?

    - by zac
    I am using wordpress as a CMS and trying to allow user fields to be input to populate the info windows in a Google Map script. I am using this to select the id and pull in the content from a custom field : $post_id = 222; $my_post = get_post($post_id); $snip = get_post_meta($post_id, 'custom-field', true); $permalink = get_permalink( $post_id ); $pass_to = '<div class="content">'.$snip.'</div><div class="moreLink"><a href="'.$permalink.'">Find out more » </a></div></div>'; var point = new GLatLng('<?php echo $lat; $lat; ?>','<?php echo $long; $long; ?>'); var marker = createMarker(point,"<?php echo $mapTitle; $mapTitle; ?>", '<?php echo $pass_to; ?>') map.addOverlay(marker); It works fine unless there is any html in the custom-field which breaks the script. I looked at htmlspcialchar and htmlentities but rather than strip everything out I would like to have it escaped so it still works and the html is intact. Any suggestions? I am pretty new to PHP and would really appreciate any pointers.

  • Function behaviour on shell(ksh) script

    - by footy
    Here are 2 different versions of a program: this Program: #!/usr/bin/ksh printmsg() { i=1 print "hello function :)"; } i=0; echo I printed `printmsg`; printmsg echo $i Output: # ksh e I printed hello function :) hello function :) 1 and Program: #!/usr/bin/ksh printmsg() { i=1 print "hello function :)"; } i=0; echo I printed `printmsg`; echo $i Output: # ksh e I printed hello function :) 0 The only difference between the above 2 programs is that printmsg is 2times in the above program while printmsg is called once in the below program. My Doubt arises here: To quote Be warned: Functions act almost just like external scripts... except that by default, all variables are SHARED between the same ksh process! If you change a variable name inside a function.... that variable's value will still be changed after you have left the function!! But we can clearly see in the 2nd program's output that the value of i remains unchanged. But we are sure that the function is called as the print statement gets the the output of the function and prints it. So why is the output different in both?
