    <p>I'm using an old random() function for creating a validation code for an AJAX commenting system I found on the web (source code at <a href="http://tutorialzine.com/2010/06/simple-ajax-commenting-system/" rel="nofollow" title="link">LINK</a> ).</p> <p>The idea behind is pretty simple: </p> <pre><code> function Random() { $chars = "ABCDEFGHJKLMNPQRSTUVWZYZ23456789"; srand((double)microtime()*1000000); $i = 0; $pass = '' ; while ($i &lt;= 4) { $num = rand() % 32; $tmp = substr($chars, $num, 1); $pass = $pass . $tmp; $i++; } return $pass; } $random_code = Random(); </code></pre> <p>and then in the form, just before the SUBMIT button: </p> <pre><code>&lt;label for="security_code"&gt;Enter this captcha code: &lt;b&gt;&lt;? echo $random_code; ?&gt;&lt;/b&gt;&lt;/label&gt; &lt;input type="text" name="security_code" id="security_code" /&gt; &lt;input name="randomness" type="hidden" id="randomness" value="&lt;?php $random_code; ?&gt;"&gt; </code></pre> <p>My AJAX commenting system uses something like this for checking if a field is blank (ie. if there are any errors): </p> <pre><code>$errors = array(); $data= array(); [...] if(!($data['name'] = filter_input(INPUT_POST,'name',FILTER_CALLBACK,array('options'=&gt;'Comment::validate_text')))) { $errors['name'] = 'Please enter a name.'; } if(!empty($errors)){ [...] } </code></pre> <p>so I wrote this: </p> <pre><code>if(!($data['security_code'] = filter_input(INPUT_POST,'security_code',FILTER_CALLBACK,array('options'=&gt;'Comment::validate_text')))) { $errors['security_code'] = 'You did not enter the validation code.'; } elseif(!($data['security_code'] = $randomness)) { $errors['security_code'] = 'You entered the validation code incorrectly. Please note that it is case sensitive.'; } </code></pre> <p>However when I click on the SUBMIT button after having inserted a random text in the validation code textfield ( test it by yourself at <a href="http://www.flapane.com/guestbook/guestbook.php" rel="nofollow" title="this link">LINK</a> ) I always get the "You entered the validation code incorrectly." message.</p> <p>print_r($_POST) gives an empty array and then the script hangs after I click on submit: Array ( )</p> <p>What am I missing? The original captcha code gets lost at some point in the validation process (the 3rd and 4th blocks of code). Thanks in advance </p>

    1. CODo you think `if(!$blah['A'] = 'B')` is different than `if($blah['A'] != 'B')` ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
