  • MySQL update query, how to skip empty values?

    - by Pawel
    I've got such query: $sql = "UPDATE test_accs SET acc_owner = '$owner_id', acc_policy_version = '$version', acc_policy_last_update = '$approved', acc_policy_next_update = '$renewed' WHERE acc_id = '1'"; Now, all of these values on the web folmular are optional, one can set one of these values, two, or so. Now, after I submit the form, it goes in the query like that: UPDATE test_accs SET acc_owner = '2', acc_policy_version = '1.2', acc_policy_last_update = '2012-12-19', acc_policy_next_update = '2012-12-18' WHERE acc_id = '1' It works only when I submit all values from the form. Can you please show me how could it work even if not all the values has been sent, just for example one of them? When I set one value (f.ex. policy version), it looks like that: UPDATE test_accs SET acc_owner = '', acc_policy_version = '1.2', acc_policy_last_update = '', acc_policy_next_update = '' WHERE acc_id = '1' and it isn't working. It might be possible cause of the acc_owner table values? #1366 - Incorrect integer value: '' for column 'acc_owner' at row 1 Thanks in advice.

  • Why should I abstract my data layer?

    - by Gazillion
    OOP principles were difficult for me to grasp because for some reason I could never apply them to web development. As I developed more and more projects I started understanding how some parts of my code could use certain design patterns to make them easier to read, reuse, and maintain so I started to use it more and more. The one thing I still can't quite comprehend is why I should abstract my data layer. Basically if I need to print a list of items stored in my DB to the browser I do something along the lines of: $sql = 'SELECT * FROM table WHERE type = "type1"';' $result = mysql_query($sql); while($row = mysql_fetch_assoc($result)) { echo '<li>'.$row['name'].'</li>'; } I'm reading all these How-Tos or articles preaching about the greatness of PDO but I don't understand why. I don't seem to be saving any LoCs and I don't see how it would be more reusable because all the functions that I call above just seem to be encapsulated in a class but do the exact same thing. The only advantage I'm seeing to PDO are prepared statements. I'm not saying data abstraction is a bad thing, I'm asking these questions because I'm trying to design my current classes correctly and they need to connect to a DB so I figured I'd do this the right way. Maybe I'm just reading bad articles on the subject :) I would really appreciate any advice, links, or concrete real-life examples on the subject!

  • Help to comment a simple statement

    - by Woppie the Russian
    How does you call this statement?: $arr = array(); initialize an array or declare an array? In brief, how would you comment such a statement? (P.S. That array would then hold a bunch of values.) EDIT: I doubt because what I basically do is declare a variable of a particular type, don't I?

  • Preventing entire JOINed MYSQL query from failing when one field is missing within a WHERE clause

    - by filip o
    I am doing a couple of joins with a variable in the WHERE clause. I'm not sure if I am doing everything as efficiently as I could, or even using the best practices but my issue is that half my tables have data for when tableC.type=500, and the other half don't resulting in the entire query failing. SELECT tableA.value1 , tableB.value2, tableC.value3 FROM tableA JOIN tableB ON tableB.id=tableA.id JOIN tableC ON tableC.id=tableB.id WHERE tableA.category=$var && tableC.type=500; What I would like to happen is to still get tableA.value1 and tableB.value2 even if there is no field in tableC with a type=500. any thoughts? i'm totally stumped as how to approach this...

    Hey, I'm using the code below to highlight some keywords in a text: $message = str_ireplace($words,'<span class="hightlighted_text">'.$words.'</span>',$message); The text may contain some html tags, for example , etc.. How can I highlight "normal" text, except the text between the html tags? Because when users search for "img" the text will be highlighted and the image doesn't work anymore.

  • Symfony form->bind fails

    - by Shawn Craver
    I'm working with a few custom forms, and one of them isn't binding it's values on a POST. I'm using the same logic for each, and only one of them isn't working. Here's the code: public function executeMediaFileUpload(sfWebRequest $request) { $this->form = new MediaFileUploadForm(); if (!$request->isMethod('POST')) $psk = $request->getParameter('psk'); else { $this->form->bind($request->getParameter($this->form->getName()), $request->getFiles($this->form->getName())); $this->logMessage('VALUE: ' . $this->form->getValue('version')); $psk = $this->form->getValue('application'); } $this->logMessage('PSK: ' . $psk); $app = Doctrine::getTable('Application')->find(array($psk)); $this->form->setDefault('application', $app->getPsk()); $this->form->setDefault('version', $app->getVersion()->getLast()->getPsk()); On the initial GET, I can see the value passed in via psk getting set as the default for application in the generated HTML, and all the values show up in the POST request in Firebug, but after I bind the form, it still contains no values.

  • Zend license restrictions with modified code

    - by Maximilian_v3
    If I'm to take parts of Zend Framework and changed them (add something, remove...), and then changed it's name, for example Zend_Config to My_Config or Zend_Application_Bootstrap to My_Application_Bootstrap, and then distribute such a code with a commercial license would I then be violating Zend's licence? If that is not an option, what can I do then? Do I need to use their code "as is" without changes if I want do distribute it with my commercial application? Tnx :)

  • Rearrange array

    - by bradenkeith
    Array starts like this: Array ( [SMART Board] => Array ( [0] => sb1 [1] => sb2 [2] => sb3 ) [Projector] => Array ( [0] => pr1 [1] => pr2 [2] => pr3 ) [Speakers] => Array ( [0] => sp1 [1] => sp2 [2] => sp3 ) [Splitter] => Array ( [0] => spl1 [1] => spl2 [2] => spl3 ) [Wireless Slate] => Array ( [0] => ws1 [1] => ws2 [2] => ws3 ) ) The keys are used as my table columns titles. Their individual arrays are to carry the column information. I have split it up even further with array_slice and array_merge_recursive to look pretty as 2 arrays - 1 holds the column names, the other looks like this: Array ( [0] => sb1 [1] => sb2 [2] => sb3 [3] => pr1 [4] => pr2 [5] => pr3 [6] => sp1 [7] => sp2 [8] => sp3 [9] => spl1 [10] => spl2 [11] => spl3 [12] => ws1 [13] => ws2 [14] => ws3 ) However, when trying to write the table I'm getting keys 0, 1, 2 as the column data, then row break then 3, 4, 5 then row break... etc. I need it to be 0, 3, 6, 9, 12 row break 1, 4, 7, 10, 13 row break etc... How can I either rearrange my array to allow for this, or rewrite how the data goes into the table so that the correct information lines up with the appropriate column? foreach(unserialize($dl->data) as $data){ //first 3 are specialinstructions, system, and room $uniques = array_slice($data,0,3); $rows = array_slice($data,3); $rows2 = array_merge_recursive($rows2, $rows); //get the specialinstructions, system, and room foreach($uniques as $unique){ echo $unique."<br/>"; }///foreach uniques echo "<br>"; }///foreach unserialized $numberofrooms = count($rows2[key($rows2)]); $numberofproducts = count($rows2); print_r($rows2); unset($rows); //write the individual rows foreach($rows2 as $header=>$rowset){ $headers[] = $header; foreach($rowset as $row){ $rows[] = $row; }//foreach rowset }//foreach rows2 echo "<p>"; print_r($rows); echo '<table class="data-table"> <caption>DL</caption> <thead><tr>'; foreach($headers as $header){ echo "<th>".$header."</th>"; } echo '</tr></thead>'; echo '<tbody>'; $i = 0; foreach($rows as $row){ if($i == 3 || $i == 0){ echo "<tr>"; $i = 1; } echo '<td>'.$row.'</td>'; if($i == 2){ echo "</tr>"; } $i++; } echo '</tbody></table>';

  • Replace duplicate values in array with new randomly generated values

    - by RussellDias
    I have below a function (created by Gordon in a previous question that went unanswered) that creates an array with n amount of values. The sum of the array is equal to $max. function randomDistinctPartition($n, $max) { $partition= array(); for($i=1; $i < $n; $i++) { $maxSingleNumber = $max - $n; $partition[] = $number = rand(1, $maxSingleNumber); } $max -= $number; } $partition[] = $max; return $partition; } For example: If I set $n = 4 and $max = 30. Then I should get the following. array(5, 7, 10, 8); However, this function does not take into account duplicates and 0s. What I would like - and have been trying to accomplish - is to generate an array with unique numbers that add up to my predetermined variable $max. No Duplicate numbers and No 0 and/or negative integers.

  • Does the order of conditions in a WHERE clause affect MySQL performance?

    - by Greg
    Say that I have a long, expensive query, packed with conditions, searching a large number of rows. I also have one particular condition, like a company id, that will limit the number of rows that need to be searched considerably, narrowing it down to dozens from hundreds of thousands. Does make any difference to MySQL performance whether I do this: SELECT * FROM clients WHERE (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar) AND company = :ugh or this: SELECT * FROM clients WHERE company = :ugh AND (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar)

  • Designing a different kind of tag cloud.

    - by animuson
    Rather than having a bunch of links that are all different sizes, I want all of my tags to be the same size. However, my goal is to minimize the amount of space required to make the cloud, aka minimizing the number of lines used. Take this example: Looks like any normal tag cloud. However, look at all that extra space around the 'roughdiamond' tag, which could be filled in by other tags like 'stone' down near the bottom, which could effectively eliminate an entire extra line from the cloud. How would I go about getting the words to fill in whatever space possible above them before starting a new line? I'm not talking about reorganizing them to find the absolute minimum number of lines required. If I was going through the list in the image, 'pendant', 'howlite', and 'igrice' would go to line 1 filling it up, 'roughdiamond' would go to line 2 because line 1 is full, 'tourmaline' would go to line 3 because it can't fit on lines 1 or 2, same with 'emberald', but 'pearl' would go to line 2 because it can fit there since there is extra space. I figure there would probably be some way of doing this in CSS that would simply cause the links to collapse into any fillable space it can fit in to.
