Passing values

[tet3828]

I am unable to retrieve the data that is sopposed to be posted by these forms.... any suggestions of why this is happening?

function edit_what () {

echo "Which value would you like to edit? <br />";
echo "<form method='post' action='{$_SERVER['PHP_SELF']}'>";
echo "<input type='hidden' name='id'  value='{$_GET['id']}'>";
echo "<input type='radio' name='edit' value='itemName'> Edit Name <br>";
echo "<input type='radio' name='edit' value='itemDesc'> Edit Description<br />";
echo "<input type='radio' name='edit' value='itemPrice'> Edit Price <br />";
echo "<input type='radio' name='edit' value='itemAvil'> Edit Avialibilty<br />";
echo "<input type=submit name=submit value=Submit /></form>";

}

Please post the script that you're using to retrieve the values.

function display_item () {


$id = $_GET['id'];
$qry = "SELECT itemName,itemCat,itemSub,itemId,itemAvil,itemPrice,itemDesc,itemSmall FROM `products` WHERE `itemId`=\"$id\"";
$result = mysql_query($qry) or die(mysql_error());

echo "Listed below is the stored data for the item #$id <br />
Use the fields below the item table to modify the information.";

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

echo "<table border=\"1\"><tr><td>".$row['itemName']."<td>Item ID# ".$row['itemId']."</td></td></tr>";
echo "<tr><td><img src=\"".$row['itemSmall']."\" /></td><td valign=top width=150>Description:
".$row['itemDesc']."</td>";
echo "</tr><tr><td>Price: $".$row['itemPrice']."</td><td>Avilibility: ".$row['itemAvil']." </td></tr>";
echo "<tr><td width=150>Catagory: ".$row['itemCat']."</td><td width=150>Sub-Catagory:".$row['itemSub']."</td></tr>";
}
echo "</table>";

It's a bit difficult to follow, but if you are talking about not being able to retrieve values after the form shown in the "edit_what()" function is submitted, it's probably because your form is a "POST" form and so $_GET['id'] becomes $_POST['id']

[tet3828]

It just "becomes" POST['id'] after it leaves the function? or do change the script to read POST['id']?

[bljepp69]

if your function "display_item()" gets called after the user clicks "Submit" on the form, then change the value for $id in the display_item() function to :

$id = $_POST['id'];

I'm just making an assumption that is how the code flows.
