cmgmyr Posted August 9, 2006 Share Posted August 9, 2006 I have a users page that has this in it:[code=php:0]function GetRandomChar() { mt_srand((double)microtime()*1000000); $IMGVER_RandVal = mt_rand(1,3); switch ($IMGVER_RandVal) { case 1: $IMGVER_RandVal = mt_rand(97, 122); break; case 2: $IMGVER_RandVal = mt_rand(48, 57); break; case 3: $IMGVER_RandVal = mt_rand(65, 90); break; } return chr($IMGVER_RandVal);}function register_form(){ global $db, $prefix, $name, $email, $username, $password, $user_taken_err, $email_taken_err, $name_taken_err, $type;if($type == "f"){ $nameout = "Your";}elseif($type == "b"){ $nameout = "Band";}else{ $nameout = "Your"; $type = "f";} session_start(); $IMGVER_TempString=""; for ($i = 1; $i <= 6; $i++) { $IMGVER_TempString .= GetRandomChar(); } $HTTP_SESSION_VARS["IMGVER_RndText"] = $IMGVER_TempString; $IMGVER_RandomText = $HTTP_SESSION_VARS["IMGVER_RndText"];echo "<div style=\"text-align:center;\"><span class=\"title\">Registration form</span><br />";echo "Fields marked with a * are required. <form id=\"RegisterForm\" method=\"post\" action=\"users.php\"> <table style=\"margin:0 auto;width:400px;\" border=\"0\" id=\"table1\" cellpadding=\"2\"> <tr> <td style=\"text-align:right;width:50%;\">$nameout Name:</td> <td style=\"text-align:left;width:50%;\"><input type=\"text\" name=\"name\" size=\"20\" value=\"$name\" /> * $name_taken_err</td> </tr> <tr> <td style=\"text-align:right;\">E-Mail:</td> <td style=\"text-align:left;\"><input type=\"text\" name=\"email\" size=\"20\" value=\"$email\" /> * $email_taken_err</td> </tr> <tr> <td style=\"text-align:right;\"> </td> <td> </td> </tr> <tr> <td style=\"text-align:right;\">Username:</td> <td style=\"text-align:left;\"><input type=\"text\" name=\"username\" size=\"18\" value=\"$username\" /> * $user_taken_err</td> </tr> <tr> <td style=\"text-align:right;\">Password:</td> <td style=\"text-align:left;\"><input type=\"password\" name=\"password\" size=\"18\" value=\"$password\" /> *</td> </tr> <tr> <td align=\"right\">Verify Image:</td> <td align=\"left\"><img src=\"doimg.php?"; echo SID."\" /><br /><input name=\"verify\" type=\"text\" id=\"verify\"></td> </tr> <tr> <td> </td> <td><input type=\"submit\" value=\"Register\" /> <input type=\"hidden\" name=\"cmg\" value=\"do_Register\" /> <input type=\"hidden\" name=\"type\" value=\"$type\" /></td> </tr> </table></form>[ <a href=\"users.php\" title=\"Back\">Back</a> ]</div>";}[/code]here is doimg.php[code=php:0]<?php$IMGVER_IMAGE = imagecreate(150,40);$IMGVER_COLOR_BLACK = imagecolorallocate ($IMGVER_IMAGE, 0, 0, 0);$IMGVER_COLOR_WHITE = imagecolorallocate ($IMGVER_IMAGE, 255, 255, 255);imagefill($IMGVER_IMAGE, 0, 0, $IMGVER_COLOR_BLACK);session_start();$IMGVER_RandomText = $HTTP_SESSION_VARS["IMGVER_RndText"];imagechar($IMGVER_IMAGE, 4, 20, 13, $IMGVER_RandomText[0] ,$IMGVER_COLOR_WHITE);imagechar($IMGVER_IMAGE, 5, 40, 13, $IMGVER_RandomText[1] ,$IMGVER_COLOR_WHITE);imagechar($IMGVER_IMAGE, 3, 60, 13, $IMGVER_RandomText[2] ,$IMGVER_COLOR_WHITE);imagechar($IMGVER_IMAGE, 4, 80, 13, $IMGVER_RandomText[3] ,$IMGVER_COLOR_WHITE);imagechar($IMGVER_IMAGE, 5, 100, 13, $IMGVER_RandomText[4] ,$IMGVER_COLOR_WHITE);imagechar($IMGVER_IMAGE, 3, 120, 13, $IMGVER_RandomText[5] ,$IMGVER_COLOR_WHITE);header("Content-type: image/jpeg");imagejpeg($IMGVER_IMAGE);?>[/code]I have used this same thing on a contact page and it works fine. When I go to register now there is just a blank black box. When I go to the contact page, that image loads fine, when I go back to register the same code appears as the contact page I was just on.Am I missing something? Do you need any other code to look at?Thanks,-Chris Quote Link to comment Share on other sites More sharing options...
onlyican Posted August 9, 2006 Share Posted August 9, 2006 the image is being cachedCommon problem, simply stop that image, or the whole page from being cached Quote Link to comment Share on other sites More sharing options...
cmgmyr Posted August 9, 2006 Author Share Posted August 9, 2006 Right, but the initial problem is that when you first go to the registration page, there is nothing in the image. There wouldn't be any caching problems if it was actually generating something...which it's not. Quote Link to comment Share on other sites More sharing options...
