Need help in getting the value of one field to be used in mysql select query

PHP
1

Hi,

I need to get the process_id or process_name to select the reject type on the table reject_list. But I don’t know how and is it possible that after I input the process_name I will get the value then it will be use in my select query to get the reject list.


<?php
  session_start();
  ob_start();
  date_default_timezone_set("Asia/Singapore");
  error_reporting(0);  
  include('connection.php');
  
 
//----QUERY FOR REJECT TYPE---//

if(isset($_SESSION['process_name']) != '')
{
    
    $process_id = $_SESSION['process_id'];
    $sql_reject = ("SELECT reject_process_id, reject_acro FROM reject_list WHERE reject_process_id = '$process_id'");

echo $sql_reject;
}
?>

        selectFirst: false
    });
    
    $("#process_name").result(function(event, data, formatted) {
        $("#process_id").val(data[1]);
    });
    
});

Any help is highly appreciated.

Thank you.

I think we need more details.

  1. What’s with the $_SESSION[‘process_name’]. When is it set?
    You have if(isset($_SESSION[‘process_name’]) != ‘’) and use $_SESSION[‘process_id’]

  2. What do you mean by:

after I input the process_name I will get the value then it will be use in my select query

The autocomplete must work independently, get values from your “get_process_list.php”.
The input will work as a simple GET request (I can see that you have no method for your form).

Now, I guess you want the autocomplete to return the name AND id so you can populate the #process_id.
After you hit the submit you’ll need to use $_REQUEST[‘process_id’] and not $_SESSION (??)

However, I never used “.result” so I’d recommend to use


    $("#process_name").autocomplete("get_process_list.php", {
       width: 205,
        matchContains: true,
        mustMatch: true,
        selectFirst: false,
        select: function(e, ui) {
             $("#process_id").val(ui.item.id); // or ui.item.value
             alert('debug: '+ui.item.id); // just for debug
        }
    });

Also, make a dubug with your console or with some alerts to check values.

Thank you… I will try it later…

I encountered problem in jquery:

‘1’ is null or not an object if the field process_name has no value or the letter that I’ve type has no match in the database.

Thank you

Check the autocomplete structure - http://jqueryui.com/autocomplete/#remote
For your autocomplete file:

<?php

// ...

$SqlResult = getFromSql( ... );
/*
// in the end $SqlResult should look like this
$SqlResult = array(
    array( 'id' => 1, 'label' => 'lbl 1', 'value' => 'val1' ),
    // ....
    array( 'id' => 23, 'label' => 'lbl 23', 'value' => 'val23' ),
);
*/
echo json_encode($SqlResult);
// ...

?>

Hi newphpcoder,

What autocomplete plugin are you using (could you post the URL)? It doesn’t look like the jQuery UI one.

Hi,

I resolved my problem by this code:


<?php
ob_start();
include "connection.php";
$q = strtolower($_GET["q"]);

if ($q == '') {
   header("HTTP/1.0 404 Not Found", true, 404);
}

//else (!$q) return;
else{
$sql = "select process_id, process_name from process_list where process_name LIKE '$q%'";
$rsd = mysql_query($sql);

$cnt = mysql_num_rows($rsd);

    if($cnt > 0)
    {
        while($rs = mysql_fetch_array($rsd)) {
	        $pid = $rs['process_id'];
            $pname = $rs['process_name'];
            echo "$pname|$pid\
";
        }
        }
    else
    {
     header("HTTP/1.0 404 Not Found", true, 404);
    }
}

?>

Thank you

  1. In my process_name i use autocomplete to ge the process_name and process_id, by that I want to get the value if process_id so I can used in my query to get all reject_type for the process_id.
    I have no idea what syntax should I used to get all the reject type based on process_id.

Thank you so much.
