Undefined index

hyster · December 28, 2010

im having problems with the initial loading of a page "Undefined index". i no the problem is due to 2 $vars having no value but i dont no how to get around the problem.

its a form that posts to itself then pulls from the database.

once you hit submit the problem goes away. i just need to sort the 1st page load out

thanks

the problem is the 1st 2 lines of the snippet.

snippet

$ser_type=$_POST['list'];
$search = $_POST['search'];
if ($search == '' || $search == ' '){

echo "Search Field is Empty - Please Input a Search Query!";
die;
}
else{
if ($ser_type=="sku"){
$sql = "SELECT * from $tbl_name WHERE sku like '%$search%' or rsku like '%$search%'";
$result = mysql_query($sql);

you need to use if(isset for the var with no value

example

if(isset( $var1 ))

Maq · December 28, 2010

Wrap the code you want to be executed in:

if(isset($_POST['submit']))
{ ...code... }

Then it will only be executed when the 'submit' button is clicked.

i got rid of the error using this

if(isset($_POST['search'])){

$ser_type=$_POST['list'];
$search = $_POST['search'];

if ($search == '' || $search == ' '){

echo "Search Field is Empty - Please Input a Search Query!";
die;
}
"rest of the code"
}

all i need to do now is figure out how to make the above "echo" to work 1st time around.

Maq · December 28, 2010

I don't get it. You want to execute:

echo "Search Field is Empty - Please Input a Search Query!";

on the very first page load?

hyster · December 28, 2010

the message was going to be changed to just " enter search" or similer.

the people who this page is aimed at are pritty dim or just play the idiot. its an for an intranet site.

Maq · December 28, 2010

Oh I see. Then have a variable defined at the top with a default message and redefine it as needed throughout your script then simply echo out the message variable.

hyster · December 28, 2010

rewrote a portion of the code and it works fine now.

thanks for your help guys.
