I'm trying to fix the Undefined index PHP notice on a wordpress site.
At the moment this is what I got:
<?php if($_SESSION['currency-select'] == "a") echo 'selected="selected"';?>
I tried to write this way but then the site goes down:
<?php if(isset($_SESSION['currency-select'] == "a")) echo 'selected="selected"';?>
Also, I have a query which is also without isset and i'm trying to fix it:
if($_SESSION['currency-select'] == 'b') {
if($_GET['pricing'] == '1') {
$args['meta_query'][] = array(
'key' => 'price',
'value' => array( '0', '250' ),
'compare' => 'BETWEEN',
'type' => 'numeric'
);
}
I tried to write:
if(isset($_GET['pricing'] == '1')) {
if($_GET['pricing']) {
but it doesn't work as well.
Thanks for your support!
Try looking if the variable isset and then check the contents of it.
if( isset($_GET['pricing']) && $_GET['pricing'] == '1' ){
//- do some magic
}
With your if-clause you check if the clause itself isset() instead of the variable.
ps: why do you check the number 1 as a string 1?
