Hi,
I'm not a specialist in program language but Data Tables help me a lot to build what I need.
Now i'm blocked on it:

<?php

// DataTables PHP library
include(  "../../DataTables_new/Original/php/DataTables.php" );

// Alias Editor classes so they are easy to use
use
    DataTables\Editor,
    DataTables\Editor\Field,
    DataTables\Editor\Format,
    DataTables\Editor\Mjoin,
    DataTables\Editor\Options,
    DataTables\Editor\Upload,
    DataTables\Editor\Validate;

//mysqli_set_charset($db,'utf8');
//$db->sql( "SET NAMES 'utf8'" );
//$db->query("SET NAMES 'utf8'")->exec();



Editor::inst( $db,'prat_listing')



    ->fields(

        Field::inst( 'ID' )->validator( 'Validate::notEmpty' ),
       

This is the part where I need help


) ->where( function ( $q ) { $q->where( function ( $r ) { $r->or_where( 'nom', $_POST['nom']); // $r->or_where( 'nom', $nom); } ); } ) ->process( $_POST ) ->json(); <?php > ``` ?> I tried to create a form where user is providing it's name and following the name provided I must have a table with some information. concerning only this user.
Continuer


Problem I tried both:

$r->or_where( 'nom', $_POST['nom']);
$r->or_where( 'nom', $nom);
```
and nothing works. so I don't know how to write it correctly :(

many thanks in advance for your help

kind regards

Philippe

    I guess the first question is, are you POSTing the nom value with the DataTables and Editor Ajax requests? ajax.data and ajax.data can be used for that.

    Thanks allan for your answer.

    No I just post my "nom" value via a form in html

    <form method="post" action="gestion_modification.php" >
     
    <label for="nom">Nom:</label>
             <input type="text"  name="nom"  placeholder="" value="">
     
             <button type="submit" class="button-submit1"> Continuer </button>
             <br><br>
     </form>
    

    To be honest I don't undrestand your question

    But I do a additional test:

    If In

    //modification.php file
    
    <form method="post" action="script_modification.php" >
    

    I replace gestion_modification.php by script_modification.php

    it works with:


    ->where( function ( $q ) { $q->where( function ( $r ) { $r->or_where( 'nom', $_POST['nom']); } ); } ) ->process( $_POST ) ->json();

    But I don't have a table only the data is diplayed.

    Modification.php is the file where I have the form and users can enter is name (nom)
    gestion_modification.php is my file where all the settings is done to built the table.
    script_modification.php is the file where I place my server request (DB request)

    So my question is how can I used the post_data value from gestion_modification.php to script_modification.php.

    I don't know if you understand, it is really complex for me to explain

                    columnDefs: [
                        { type: "num-html", targets: 4 }

    This is not a data tables related issue and I am afraid you can't expect any help on stuff like this in this forum. Sorry. But let me give it a try:

    You need to understand the difference between a $_POST and a $_SESSION variable. Read the PHP docs please or take an online course. There are many of them.

    Here is an example:
    Upon log in I save the id of the user in a session variable that I use later on in Editor queries as well. This certainly would not work with a $_POST variable.

    I call my login function and save a couple of session variables if login was successful

    $r = login($parm, $dbh);
    // if session id is set this means login was successful
    if ($r['isOk']) {
        $_SESSION['id'] = $r['id'];
        $_SESSION['type'] = $r['type'];
        $_SESSION['role'] = $r['role'];
    }
    

    Upon logout the session variables are deleted:

    function logout () {
        session_destroy();
        $_SESSION = [];
    }
    

    I can use the session variables in Editor as well:

    e.g.
    
    ->where( function ( $q ) {        
        $q  ->where( 'report.user_id', $_SESSION['id'] );
        $q  ->where( 'report_type.user_id', $_SESSION['id'] );
    } )

    thanks a lot for your answer. Ok I think that I understand the variable "nom" is already used in the second file, so When I call it in the third page, it doesn't exist anymore.
    so I may used $_SESSION to keep the variable in my entire process.

    I will try it directly

    thanks so much to have answe :)
