string replace in upload sql

I'm uploading images to my server and also using those form fields to update my database. Because of the way the front end is already built, I need to strip the file extensions before they update my database. In other words I need "myimage" not "myimage.jpg".

It looks like I need to use string replace but I'm not savvy enough to pull it off - how would i add a string repliace to this update statement?l
$updateSQL = "UPDATE ".$thumbs_table." SET
".((trim($_POST['thumb1'])) != '' ? "thumb1=".GetSQLValueString($_POST['thumb1'], "text")."," : "")."
".((trim($_POST['thumb2'])) != '' ? "thumb2=".GetSQLValueString($_POST['thumb2'], "text")."," : "")."
".((trim($_POST['thumb3'])) != '' ? "thumb3=".GetSQLValueString($_POST['thumb3'], "text")."," : "")."
".((trim($_POST['thumb4'])) != '' ? "thumb4=".GetSQLValueString($_POST['thumb4'], "text")."," : "")."
description=".GetSQLValueString($_POST['description'], "text").",
DrID=".GetSQLValueString($_POST['DrID'], "text")."
WHERE case_id=".GetSQLValueString($_POST['case_id'], "int");

Insert this "foreach" iterator before the query creation.  It will look for anything in the posted form that is named starting with "thumb."  For those values it will remove the suffix ".jpg" from the end and it will replace those values with the new, truncated, name.

HTH, ~Ray
foreach ($_POST as $key => $value)
{
    if (substr($key,0,5) == 'thumb')
    {
        $value = eregi_replace("\.jpg$", '', $value);
        $_POST[$key] = $value;
    }
}
 
$updateSQL = "UPDATE ".$thumbs_table." SET
".((trim($_POST['thumb1'])) != '' ? "thumb1=".GetSQLValueString($_POST['thumb1'], "text")."," : "")."
".((trim($_POST['thumb2'])) != '' ? "thumb2=".GetSQLValueString($_POST['thumb2'], "text")."," : "")."
".((trim($_POST['thumb3'])) != '' ? "thumb3=".GetSQLValueString($_POST['thumb3'], "text")."," : "")."
".((trim($_POST['thumb4'])) != '' ? "thumb4=".GetSQLValueString($_POST['thumb4'], "text")."," : "")."
description=".GetSQLValueString($_POST['description'], "text").",
DrID=".GetSQLValueString($_POST['DrID'], "text")."
WHERE case_id=".GetSQLValueString($_POST['case_id'], "int");

If you also wanted to remove '.png' suffixes, you would add a statement like this to the script after line 5.  You could follow a similar pattern for other suffixes you might want to remove.

Best regards, ~Ray
        $value = eregi_replace("\.png$", '', $value);

hi ray - thanks so much for this! just so i'm straight:

will this iterator remove ".jpg" from all records i'm inserting using this form? in other words, if i insert "bla.jpg" will the ".jpg" be stripped or does it have to be "thumbbla.jpg" ?

foreach ($_POST as $key => $value)
{
    if (substr($key,0,5) == 'thumb')
    {
        $value = eregi_replace("\.jpg$", '', $value);
        $_POST[$key] = $value;
    }
}

The $_POST array is a superglobal associative array.  Let's deconstruct that terminology.

"Superglobal" means that it is available in ALL namespaces and variable scope.  You can use it inside classes and functions without an special consideration - just address it.

"Associative" means that an array has textual keys associated with each value.

Read up on the foreach() command on the PHP web site.  It shows you how to work with associative arrays.  The code above tests to see if the KEY starts with the character string "thumb."  The KEY comes from the HTML form. It is the "name=" in the <input type=text> statement.

Does that help clear it up?

Best, ~Ray
