UPDATE: I narrowed it down, when I got rid of this tag in the header.php file it all works, can someone please explain this.

<script src="#" type="text/javascript"></script>

Hi I’m having quite an annoying issue with my php code. I am trying to update a php database, from a form, when I do this however the fields in the data base become empty after submitting. Please Help! You can view it in action here http://andcreate.com/shoelace/admin/edit1.php click on the lists on the right to edit them and see what happens.

<?php
include("header.php");

echo "<h2>Edit Posts</h2>";

echo "<div id='editNav'>";
echo "<p>Choose Post to Edit</p>";




//////////GET ALL RECORDS AND BUILD A NAV SYSTEM FROM THEM////////
$results = mysql_query("SELECT * FROM shoeData ");



while($row = mysql_fetch_array($results)){




 $id = $row['id'];
 $name = $row['name'];
 $about = $row['about'];

 echo "$date <a href=\"" . $_SERVER['PHP_SELF'] . "?id=$id" . "\">" . substr($name, 0, 40) . " </a> <br/> ";


 }

$thisID = $_GET['id'];

if(!isset($thisID)){
 $thisID = 22;

}




//////////FINISH ALL RECORDS AND BUILD A NAV SYSTEM FROM THEM////////

echo "</div>";



///////IF USER SUBMITS CHANGES UPDATE THE DATABASE//////////
//has user pressed the button
$update = $_GET['update'];

if($update == "yes") {

 $name = $_POST['name'];

 $about =  $_POST['about'];

 $company =  $_POST['company'];

 $buy =  $_POST['buy'];



 //update data for this record
 $sql = "UPDATE shoeData SET 
 name = \"$name\",
 about = \"$about\",
 company = \"$company\",
 buy = \"$buy\"
 WHERE id= $thisID";
 $thisUpdate = mysql_query($sql) or die(mysql_error());


}




///////END IF USER SUBMITS CHANGES UPDATE THE DATABASE//////////




/////////// HERE WE GET THE INFO FOR ONE RECORD ONLY//////// 
$results = mysql_query("SELECT * FROM shoeData WHERE id=$thisID");



while($row = mysql_fetch_array($results)){


 $name = $row['name'];

 $about = $row['about'];

 $company = $row['company'];

 $buy = $row['buy'];

}
//////////////FINISH GETTING INFO FOR ONE RECORD ONLY/////////////

    You have $update = $_GET['update'];, but then right after that, you’re using $_POST. A given request is either GET or POST, not both – thus whenever $_GET['update'] is set to “yes”, there aren’t going to be any POST vars set, and thus the update will be done with all of the values it’s setting blank.

    Chances are you actually meant to use either $_GET or $_POST in both places – since your updates are going through, but are blank, it sounds like you want to use $_GET (though for form submission/updates, you should probably really be using POST instead).
