    <p>I can not display <code>captcha</code> that is outside of root in my shared server. My <code>html</code> page:</p> <pre><code>&lt;img align="top" id="captcha" src="&lt;?=ROOT_PATH.$this-&gt;editPath;?&gt;function/security_code.php?&lt;?=mt_rand(100, 9999);?&gt;" /&gt; </code></pre> <p>it work fine in <code>localhost</code>.<br> and <code>security_code.php</code> is :</p> <pre><code>header('Content-Type: image/jpeg'); session_start(); class captchaGD { public $font='arial.ttf'; public function generateCode($characters) { $possible = '23456789bcdfghjkmnpqrstvwxyzBCDFGHJKMNPQRSTVWXYZ'; $code = ''; $i = 0; while ($i &lt; $characters) { $code .= substr($possible, mt_rand(0, strlen($possible)-1), 1); $i++; } return $code; } function __construct($width='120',$height='40',$characters='6') { $code = $this-&gt;generateCode($characters); $font_size = $height * 0.5; $image = imagecreate($width, $height) or die('Cannot initialize new GD image stream'); $background_color = imagecolorallocate($image, 255, 255, 255); $text_color = imagecolorallocate($image, 20, 40, 100); $noise_color = imagecolorallocate($image, 100, 120, 180); for( $i=0; $i&lt;($width*$height)/3; $i++ ) { imagefilledellipse($image, mt_rand(0,$width), mt_rand(0,$height), 1, 1, $noise_color); for( $i=0; $i&lt;($width*$height)/200; $i++ ) { imageline($image, mt_rand(0,$width), mt_rand(0,$height), mt_rand(0,$width), mt_rand(0,$height), $noise_color); } $textbox = imagettfbbox($font_size, 0, $this-&gt;font, $code) or die('Error in imagettfbbox function'); $x = ($width - $textbox[4])/2; $y = ($height - $textbox[5])/2; imagettftext($image, $font_size, 0, $x, $y, $text_color, $this-&gt;font , $code) or die('Error in imagettftext function'); imagejpeg($image); imagedestroy($image); $_SESSION['security_code']['form']=""; $_SESSION['security_code']['form'] = strtolower($code); } } $width = '120'; $height = '40'; $characters = '3'; $captcha = new captchaGD($width,$height,$characters,$_SERVER['REQUEST_URI']); </code></pre> <hr> <p><strong>Edit</strong>: According to comment, does it work fine If i put <code>security_code.php</code> in <code>public_html</code>? is it safe way?What better way to do this?</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
