  • Is it best to make fewer calls to the database and output the results in an array?

    - by Jonathan
    I'm trying to create a more succinct way to make hundreds of db calls. Instead of writing the whole query out every time I wanted to output a single field, I tried to port the code into a class that did all the query work. This is the class I have so far: class Listing { /* Connect to the database */ private $mysql; function __construct() { $this->mysql = new mysqli(DB_LOC, DB_USER, DB_PASS, DB) or die('Could not connect'); } function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $info = $result->fetch_object() or die('Could not create object'); return $info; } } This makes it easy to access any info I want from a single row. $listing = new Listing; echo $listing->getListingInfo('','Books')->title; This outputs the title of the first listing in the category "Books". But if I want to output the price of that listing, I have to make another call to getListingInfo(). This makes another query on the db and again returns only the first row. This is much more succinct than writing the entire query each time, but I feel like I may be calling the db too often. Is there a better way to output the data from my class and still be succinct in accessing it (maybe outputting all the rows to an array and returning the array)? If yes, How?

  • Read external HTML page and then find data within

    - by inthewayboy
    I'm playing around with an idea, and I'm stuck at this one part. I want to read an external HTML page and then extract the data held within two <dd> tags. I've been using file_get_contents with good results, but I'm at a loss as to how to accomplish that last part. The two tags I want to extract the value from are always enclosed within a particular <div>, was wondering if that might help? In my mind it reads the entire html file into a string, then dumps all the data up until this one particular <div>, and dumps all the data after the closing </div>. Is that possible? I think this needs regex syntax which I've never used yet. So any tips, links, or examples would be great! I can provide more info as necessary.

  • How to handle redirections with codeigniter?

    - by SinneR
    Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

  • What statistics app should I use for my website?

    - by Camran
    I have my own server (with root access). I need statistics of users who visit my website etc etc... I have looked at an app called Webalyzer... Is this a good choice? I run apache2 on a Ubuntu 9 system... If you know of any good statistics apps for servers please let me know. And a follow-up question: All statistics are saved in log-files right? So how large would these log-files become then? Possibility to split them would be good, dont know if this is possible with Webalyzer though...

  • <div class="headerFst"> What is this?

    - by Jessica
    I have been attempting to remove a repeating header on all of my webpages for customization purposes, but have been unsuccessful finding what is causing this header repeat. I came across this code in the header, and after researching it, I can not find what its purpose is. Could this be my culprit for the repeating patterns? If not, please point me to the right direction. Here is the hmtl: <!--container--> <div id="container"> <div id="header"> <!--headerFst--> <div class="headerFst"> and here it is in look.css: div.headerFst { float:left; width:980px; padding-top:5px; } Thank you for viewing, and helping if possible.

  • How do I remove unnecessary options from a select field in a Drupal form?

    - by thismax
    I'm using the better_exposed_filters module to create a set of exposed filters for a view. One of the filters is being displayed as a select field, and I would like the field to only display options that are actually associated with content in the database. Currently, I am doing this using the hook_form_alter() method. For simplification, in the following example the field is called 'foo' and the content type with that field is called 'bar': function my_module_form_alter(&$form, $form_state, $form_id) { // Get all the values of foo that matter $resource = db_query('select distinct field_foo_value from {content_type_bar}'); $foo = array(); while($row = db_fetch_object($resource)) { $foo[$row->field_foo_value] = $row->field_foo_value; } $form['foo']['#options'] = $manufacturers; } This works great -- the form displays only the options I want to display. Unfortunately, the view doesn't actually display anything initially and I also get the following error message: An illegal choice has been detected. Please contact the site administrator. After I filter options with the form once, everything seems to work fine. Does anyone know how I can solve this problem? I'm open to an entirely different way of weeding out filter options, if need be, or a way that I can figure out how to address that error.

  • Conditional fieldgroups/fieldsets in Drupal 7

    - by seane
    Background: In Drupal 7, I have created a form with CCK (aka the Field UI). I used the Field group module to create a fieldgroup, but I need it to be conditional, meaning it will only display depending on a previous answer. Previous research: To create a conditional field, you can use hook_form_alter() to edit the #states attribute like so: function MYMODULE_form_alter(&$form, &$form_state, $form_id) { if ($form_id == 'person_info_node_form') { // Display 'field_maiden_name' only if married $form['field_maiden_name']['#states'] = array( 'visible' => array( ':input[name="field_married[und]"]' => array('value' => 'Yes'), ), ); } } However, there seems to be no way to use the States API for fieldgroups. One thing to note is that, while fields are stored in $form, fieldgroups are stored in $form['#groups'] as well as in $form['#fieldgroups']. I don't know how to distinguish between these, and with this in mind, I have tried to apply a #states attribute to a fieldgroup in the same manner as above. However, it only produces server errors. Question: Is there a way to make a fieldgroup display conditionally using the States API or some alternative approach?

  • Why don't paid for systems work properly? [closed]

    - by Kyle Sevenoaks
    Why when you buy a online store system that's advertised as Easy for you to manage and allows to change and tweak the look of store pages with unseen ease is it exactly the opposite? When you're offered six months free support do you never get an answer and finally when you make layout changes to one page, does a completely unrelated business logic completely break down? So really two questions: Why do authors of such systems put them up for sale before they're completed? How to exact revenge on said author? Thanks.

  • Updating multiple rows with an array

    - by Copephobia
    I have a table that holds user information. One of the columns holds the position of the user in the game they are in. When a game is being created, I need to update the positions of the users of each team. Here is an example: Game id : 7 Team 1 users : 1,2 Team 2 users : 3,4 team1_position : array(1,2) team2_position : array(13,14) What I want to do is update the user table using the array of positions in the SET area. My goal is to be able to update the users without the need for their id (I have different size game boards, so I have multiple position arrays for each board size) How can I do something like this: UPDATE user SET position='(team1_position)' WHERE game = '7' AND team = '1' I feel like it would be a waste of resources to select all the id's of each team and update them separately.

  • Why does this basic class not work?

    - by kalaba2003
    I could not understand why my class does no t work. Returns nothing. Is there any mistake? class User { public $first_name; public $last_name; public function full_name() { if(isset($this->first_name) && isset($this->last_name)) { return $this->first_name . " " . $this->last_name; } else { return "No name!"; } } public function assign () { $this->first_name = "Name"; $this->last_name = "Surname"; } } $user = new User(); $user->assign(); $user->full_name(); ?>

  • Saving variables (not sessions)

    - by james.bcn
    This may be a silly question, but how do I save variables that are not specific to a particular session. An simple example of why you might want to do this would be a visitor counter - a number that increases by one each time someone visits a web page (note - I'm not actually doing that, my application is different, but that is the functionality I need). The only ways I can think of doing this are either writing the variables to a file, or putting the variables into a database. Both seem a bit inelegant. Is there a better way to to this kind of thing?
