if statement and URL passed variable problems

[Darkmatter5]

Here's the executed code:

<?php
function ret_info($search,$type,$field_id,$field) {
  include 'library/config.inc.php';
  $conn=mysql_connect($dbhost, $dbuser, $dbpass) or die('Error connecting to mysql');
  mysql_select_db($dbnamemain);
            
  if($type=="cabinets") { $ident="cabinet_id"; }
  elseif($type=="folders") { $ident="folder_id"; }
  elseif($type=="items") { $ident="item_id"; }
  if(isset($_POST['cab_load']) || isset($_GET['cabinet_id'])) {
    if(isset($_GET['cabinet_id'])) { $field_id==$_GET['cabinet_id']; }
      if($search=="data") {
        /*$query="SELECT $field
                 FROM $type
                 WHERE $ident=$field_id";
        $result=mysql_query($query) or die ($query. '<br>' .mysql_error());
        $row=mysql_fetch_array($result);
        echo $row[$field];*/
        echo $_GET['cabinet_id']. "<br>";
        echo "field_id: $field_id<br>";
        echo "search: $search<br>";
        echo "type: $type<br>";
        echo "field: $field";
      } elseif($search=="count") {
        /*$query="SELECT $ident
                  FROM $type
                  WHERE $field=$field_id";
        $result=mysql_query($query) or die ($query. '<br>' .mysql_error());
        $count=mysql_num_rows($result);
        echo $count;*/
      }
    } else { echo ""; }                            
                                      
    mysql_close($conn);
}
?>

 

Here's the code that runs the above code

<?php $ec->ret_info(data,cabinets,$cabinet_id,cab_name); ?>

 

And here's the URL variable "...myurl/res_detcab.php?cabinet_id=2 "

 

Now here's the output:

2

field_id:

search: data

type: cabinets

field: cab_name

 

Why is field_id not being set? How can I fix this?

[CroNiX]

$field_id==$_GET['cabinet_id'];

should be

$field_id=$_GET['cabinet_id'];

since you are assigning a value and not comparing them there.
