Undefined index - understanding

[aquaticdave]

Hi all,
My first post and hopefully in the right place.

I run a php pro bid script great script and it's been fully modified.

On getting ther and having the site run live i suddenly found the error logs.

Ouch they were huge. I am now trying to go through and corrrect each and every problem.

i have a lot of Undefined index i do not understand what these even mean.

here is an example
PHP Notice: Undefined index: state_select in /var/www/vhosts/mysite.co.uk/httpdocs/templates/search_browse_box.tpl.php on line 185

the code for the line is

<option value="2189" <? echo ($src_details['state_select'] == '2189') ? 'selected' : '';?>>East Lothian</option>

what could possibly be wrong with that, and why can't i see it?

Many thanks for your help in advance.

Regards Dave

To also add to this rather than open a new post i get the following

PHP Notice: Use of undefined constant IN_ADMIN - assumed 'IN_ADMIN' in /var/www/vhosts/mysite.co.uk/httpdocs/includes/functions.php on line 307

Code is as follows

$file_extension = (IN_ADMIN == 1) ? '../' : ''; 

should this be

$file_extension = ("IN_ADMIN" == 1) ? '../' : ''; 

instead?

again thanks for your help in advance.

Adding the "/s dosent change anything besides making the constant be interpreted as plain text

Id say you either initialized it incorrectly or its not global.

Where did you initialize the constant At?

(i should warn you im no master at Constants :P)

Undefined Index usually shows itself when a variable is not set or does not exist

this part

$src_details['state_select'] 

state_select is probably not set in that array or the array is not there, you should use

$var = print_r($src_details);
echo '<pre>'.$var.'</pre>'; 

And see if its even there.

Hi Nvenom,
Thank you for replying so quick.
the line

$file_extension = (IN_ADMIN == 1) ? '../' : ''; 

seems to start here?

function page_order($file_path, $order_field, $start, $limit, $other_params, $field_name = null)
{
    (string) $display_output = null;

    $file_extension = (IN_ADMIN == 1) ? '../' : '';
    $alt = false; 

I have not changed this part of the code so this was a PPB thing.
I seem to have a lot of errors in the log that are very similar to the above, if it is not about ADMIN it is also about AJAX instead. Maybe they are not set globaly but i'm not sure.

as for the line

<option value="2189" <? echo ($src_details['state_select'] == '2189') ? 'selected' : '';?>>East Lothian</option>

it starts off like.

<select name="state_select" class="src_input"> 

the comand runs as it should as regards to searching each county but i am getting this error instead.

If i am honest i do not know where to place

$var = print_r($src_details); 
echo '<pre>'.$var.'</pre>'; 

to see if it's there.

I am a novice really at php i can admit that and i am doing my best at learning but i am finding it hard, Maybe i jumped the gun a bit trying to jump straight in.
I have a problem reading books and find i learn being more practicle having an a problem and learning from there. I'm sorry if it seems like i'm being a fool but i really am trying and the site has come a long way from the stock site it was.

Again thank you for your help

Regards Dave

As for IS_ADMIN, That pretty much confirms that its a global issue, im not sure how it structured so its up to you to find where it is set at in the midst of all your the code and make it Global, Or pass it into the function when its called (might work :P) Like

//I added a new first variable that gets read when the function gets called
function page_order($ina, $file_path, $order_field, $start, $limit, $other_params, $field_name = null) 
{ 
    (string) $display_output = null; 

    $file_extension = ($ina == 1) ? '../' : ''; 
    $alt = false;

   //rest of your code.. 

and than you would call that function like

page_order(IN_ADMIN,'','','','','','');
// The '' are just other data that would get passed along with the function 

And For the

<?php
$var = print_r($src_details); 
echo '<pre>'.$var.'</pre>';
?>

You would just put that below the <select></select> that your having issues with
