PHP - Help Passing Variable Into Next Page
Hello,
I'm trying to build a small project; and as part of it - I want users to search and when presented with relevant enteries in the SQL database - they should be able to click and retrieve a page dedicated to that entity. The problem I am having is in passing the 'id' of the search result onto the next (description) page. Code: [Select] $SQL = "SELECT * FROM loads"; $result = mysql_query($SQL); while ($db_field = mysql_fetch_assoc($result)) { $clickid = $_GET['id']; print $db_field['id'] ."<a href=\"load_info.php?id=$id" . $id . "\" target=\"_self\" title=\"\">More Info</a>;"; print $db_field['depart:'] . "<BR>"; print $db_field['dest'] . "<BR>"; } I thought it was easy enough to pass the variable like above ("load_info.php?id=$id) and then grab it on the next page like so: $val = $_GET['clickid']; Unfortunately, it doesn't retrieve the info from the page before. If I insert a number in there, it does work correctly, but I really need the ID of the database entry to pass on so as to provide the user with further information. If anyone could help it would be appreciated. L. Similar Tutorialsi have this code in a form, i need to pass a variable $time to next page, how can i do that ? if( $sErr ) print "<script language='javascript' type='text/javascript'>location.href='#error';</script>";;; else: print "<script language='javascript' type='text/javascript'>location.href='paypal.php';</script>";;; id not passing onto next page. when i view the source code the id value is there. <a href='view_designs2.php?id='198'> but when the next page loads there is nothing in the address bar. Code: [Select] <?php echo "<table width='1000' align='center'>"; $data=mysql_query("SELECT * FROM design WHERE jobno='$id' AND status!='rejected'") or die (mysql_error()); $counter = 0; while ($info=mysql_fetch_array($data)){ $img5=$info['name']; $id=$info['id']; $img=$info['thumbs']; echo "<td>"; echo "Design By "."$img5 "."<br><br>"; echo "<a href='view_designs2.php?id='$id'><img src='../dthumbs/$img' style='text-align: center; width:250px; max-height:250px; border: solid 10px; border-radius: 5px; border-color:tan; -moz-box-shadow: 3px 3px 4px #000; -webkit-box-shadow: 3px 3px 4px #000; box-shadow: 3px 3px 4px #000; -ms-filter: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000'); filter: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000'); ''>"; echo "<br><br></td>"; $counter = $counter + 1; if ($counter==3){ echo "<tr>"; $counter=0; } } echo "</tr></table>"; ?>' So i got the following problem: i got some pages : index.php , comment.php, viewArticle.php When i try to submit something from comment.php appear a error "Undefined variable:result" The var result is defined in index.php When i click on one article from the list the function viewArticle() is requiring viewArticle.php and the function addcomment() is requiring comment.php The addcomment function() is in viewArticle function() I can't figure out what's wrong but I guess have something to do whit the form action="index.php?action=viewArticle&articleid=<?php echo $result['article']->id?>" index.php code Code: [Select] <?php include('config.php'); $action = isset($_GET['action'])?$_GET['action']:""; switch($action) { case 'viewArticle':viewArticle();break; default:homepage(); } function homepage() { $result = array(); $data = Article::getlist(1); $result['article']=$data['result']; $result['total']=$data['totalrows']; require('homepage.php'); } function viewArticle() { if( !isset($_GET['articleid']) )homepage(); $result = array(); $result['article'] = Article::getbyid((int)$_GET['articleid']); $result['name'] = $result['article']->name; addcomment(); require('viewArticle.php'); } function addcomment() { if(isset ($_POST['submit'] )) { $comment = new Comment; $set = array(); $set['usern']="HJhj"; $set['com']="aca wqeq"; $set['page']=7; $comment->storeFormValues($set); $comment->insertc(); } else require('comment.php'); } ?> viewArticle.php code Code: [Select] <center> <h1> <?php echo $result['article']->text ?> </h1> comment.php code: Code: [Select] <form method='post' action="index.php?action=viewArticle&articleid=<?php echo $result['article']->id?>" > <input type="hidden" name="id" value="56"/> <ul> <li> <input type="text" name="usern" id="usern" /> </li> <li> <textarea name="com" id="com" COLS=40 ROWS=6></textarea> </li> <input type="hidden" name="page" value="56" /> <input type="submit" name="submit" value="submit" /> </form> Hi all, I have my whole script working only the name of the upload file won't pass to the process.php page.

Yesterday, it quit working (403 permissions error). After a long bout of trouble-shooting, I found out that it has something to do with mod_security that they have suddenly enabled (have no idea as I'm not a Linux guy). They told me they fixed the problem on my domain by whitelisting it as an exception, but strangely, even though the permissions error went away, the actual src= box of the iframe, which was the url variable I was passing in the url, no longer loads. So.. I'm trying to break this down into the simplest form to figure it out. I just understand php basics so needing some verification that I'm doing this right/wrong. Here's my code.. page1.php Code: [Select] <? $testurl = "http://google.com"; ?> <a href="http://mysite.blah/page2.php?url=<? echo $testurl; ?>">page2.php</a> page2.php Code: [Select] if (isset($_GET['testurl'])) echo $testurl; else echo "sorry dude"; I am only able to print "sorry dude". Am I doing something wrong or shouldn't this send the url? Thanks for the help! hello all, I'm new here and I'm learning mysql/php. Currently I have a dynamic table on one of my webpages, and the loop code looks like this:while ($i < $numRows) { $fname = mysql_result($result, $i, "fname"); $fcode = mysql_result($result, $i, "fcode"); $ftype = mysql_result($result, $i, "ftype"); $fdesc = mysql_result($result, $i, "fdesc"); ?> <tr> <td><a href="showfunction.php?fname=<?php echo "$fname"; ?>" target="_self"> <?php echo "$fname"; ?></a></td> <td> <?php echo "$fdesc"; ?> </td> <td><div align="center"> <?php echo "$ftype"; ?> </div></td> </tr> <?php $i++; } ?> what I would like to do is pass the ''fname'' variable to the "showfunction" page so it can printed from the database. Here is the relevant portion of the page:<body><div class="codeblock"> <div class="title">Code:<br /> </div><code><pre> <?php echo $fcode; ?> </pre></code></div> <br /><pre><hr /> </pre> I know that doesn't work, and I didn't expect it to because there is no way to 'get' the 'fname' variable from the preceeding script. I do not want to use the GET method with this because from what I understand, you can only use it with Forms. I really don't want to put controls in all of my table fields just to be able to pass the function name to the next page. Does that make sense? If I could get a jumpstart on this one last hurdle, I would appreciate it. thank you so much! Cheers. How, if possible, can a $varĀ be passed to theĀ forms action php file?

'"/><?php } } ?> The recieving script <?php $str2=$_GET['$str']; $image = ImageCreateFromPNG("http://localhost:8888/wordpress_3/wp-content/plugins/Authors2/jackets/GDL.png"); $color = imagecolorallocate($image, 0xFF, 0xFF, 0xFF); $colorShadow = imagecolorallocate($image, 0x66, 0x66, 0x66); $font = 'Tahoma.ttf'; $fontSize = "10"; $fontRotation = "0"; $str= "Successful Home Catering"; /* Shadow */ ImageTTFText($image, $fontSize, $fontRotation, 27, 22, $colorShadow, $font, $str ); /* Top Level */ ImageTTFText($image, $fontSize, $fontRotation, 25, 20, $color, $font, $str); ImageTTFText($image, $fontSize, $fontRotation, 25, 100, $color, $font, $str2); header("Content-Type: image/PNG"); ImagePng ($image); imagedestroy($image); ?> hey ive got a page that lists a users bank accounts...when the user chooses to update an account it goes to a new page where they can edit the details...when it goes to this new page it takes the user's ID and the account ID with it in the URL (http://localhost/oswp/bank/updateaccounts.php?id=34&cid=1) so i know these variables are correctly being transferred. now when the user has made their changes and clicked the update button it should update the database and then re-locate back to the original page listing all accounts...to get back to this page and show the correct accounts for that user i thaught i needed to take the ID from the URL...give it a variable...and use it in the URL back to the original page. so for example the variable and update sql and re-locate code would look like this. $cid = $_GET['cid']; //updating the table $result=mysql_query("UPDATE accounts SET accno='$accno', pin='$pin', type='$type', name='$balance', balance='$balance', active='$active' WHERE accid=$id"); header("location:accounts.php?id=$cid"); however currently when the user clicks update and it tries to relocate back to the original page its not getting the variable in the URL. (http://localhost/oswp/bank/accounts.php?id=) and im getting the errors: Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\uni\oswp\assignment\bank\accounts.php on line 26 's bank accounts Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\uni\oswp\assignment\bank\accounts.php on line 30 basically saying its expected a number up in the URL and its not finding one...but i dont know why...any ideas please its quite urgent. here is the relevant code for this section: Accounts.php: <a href="adminlogout.php">Logout</a><br /> <?php $id = $_GET['id']; if(!isset($_SESSION['myusername'])) { header("location:adminlogin.php"); } $dbhost = 'localhost'; $dbuser = 'root'; $dbpass = ''; $db = 'bank'; $conn = mysql_connect($dbhost,$dbuser,$dbpass); mysql_select_db($db); $result = mysql_query("SELECT * FROM customer WHERE cusid=$id"); $row2 = mysql_fetch_array($result); echo $row2['name'] .
