Function that checks if a segment key exists ? - El Forum - 10-12-2007
[eluser]starbbs[/eluser]
Call me stupid but i need a function that simply returns the key if this key exists inside the URI class. I cannot seem to fin it. Let me explain:
Code:
/**
* This returns true, even is the segment does NOT exist. Example:
*
* $segment = array( 1 => 'cpanel',
* 2 => 'admin',
* 3 => 'module',
* 4 => 'user',
* 5 => '44');
*/
// In my code, i use this to get the value:
$segVal = $this->uri->segment(6, 0);
// If all goes well, $segVal contains FALSE. but when i do:
$segVal = (is_numeric($this->uri->segment(6, 0)) ? TRUE : FALSE;
// Now segVal contains TRUE !So, i was thinking that there might be a function, in where i can check for a key directly. But i cannot find this function. I created my own function. Maybe someone can think of a faster way:
Code:
// $name = the name of the segment you want to check
// $return_index = When set to true, it returns the index of $name
// When set to false, it returns $name when found
// result: when found, the name or it's key, when nothing is found, it returns false
function nsegment($name, $return_index = FALSE )
{
if( in_array( $name, array_values($this->router->segments)))
{
foreach($this->router->segments as $segmentidx => $value ) {
if($name == $value) {
if($return_index){
return $segmentidx;
}else return $value;
}
}
}else
return FALSE;
}
/* $cpanelidx contains '3' */
$cpanelidx = $this->CI->uri->segmentn('module', TRUE);
/* $cpanel contains 'module' */
$cpanel = $this->uri->nsegment('module');If you have any suggestion for my problem, please reply!

You use the second argument of the segment method, this means if the 6th segment is not found 0 will be returned so your is_numeric check will always be true.
