    Answer ✓

    When you link to my example as a test case, are you saying the error can be seen on that page? It appears to work okay for me. Or do you mean you are using that same code on your PHP 5.3 server and it is causing issues?

    PHP 5.3 is ancient and stop receiving security updates in 2014!

    However, the update is fairly straightforward. 5.4 gained the ability to use Javascript like array syntax, so array() could be written as [].

    For example, the echo could be written as the following in PHP 5.3 code:

    echo json_encode(array(
      'options' => array(
        'team.country' => $countries
      )
    ));
    

    You need to also update the other array constructors, such as on the select line to make it PHP 5.3 compatible.

    But honestly - upgrade. It's worth it! ;)

    I have the type2 and type3 fields in the myorder table.

      id     ddbh       type2       type3  .........
      438   el1902    Outdoor   Fashio
    

    These two fields are linked and their association is based on the myservice table. The myservice table structure is as follows

    If you could link to a page showing the issue that would help be debug it and offer you some help.

    I need to know what is being submitted to the server when you change the type2 field.

    My guess is that the query condition:

    array('name' => $_REQUEST['values']['myorder.type2'])
    

    is what is causing the issue.

    The TYPE3 output in the table now represents the entire value of the NAME2 field in the SERVICESHOW4 table corresponding to TYPE2, such as Mountaineering, Fashion, Leisure, and Sport. However, what I want is one of the values, such as Sport. I know to use explore and array to separate it, but I don't know where to separate it

    I'm finding this really hard to picture I'm afraid. Can you give me a link to the page please?

    I'm not clear if the issue is still that contries2.php is still returning an empty data array when you select a value, or something else?

    That page is giving errors I'm afraid - it looks like jQuery isn't being loaded:

    Could you take a look at that, please.

    Thanks for the updated link. You don't need to bump your thread just a few hours after posting :).

    Assuming that countries2.php is up to date, then, because the response from the server is simply [], then it must be falling into this part:

    $values = $_REQUEST['values']['ocorder.type2'];
    if ( $values) {
        echo json_encode(array() );
     
        return;
    }
    

    I can see in the request Editor is sending:

    values[ocorder.type2]:  "运动"
    

    So something somewhere is going wrong with the $_REQUEST is my guess. Can you add: print_r($_REQUEST); to your script, just before the echo json_encode(array()); perhaps?

    Based on that, $values should be 鏃惰. Which has just let me to the error:

    if ( $values) {
          echo json_encode(array() );
          return;
    }
    

    The if condition should be if (! $values) { !!

    Thank you. It is already possible to link, but now the output name2 is a set of numbers. What I want is that name2 is also a selection box, and the options in the selection box are separated by ",". At which position should we use the split function to separate this

  • allanallan Posts: 61,972Questions: 1Answers: 10,160 Site admin

    It looks like countries2.php is now returning data.

    What I want is that name2 is also a selection box, and the options in the selection box are separated by ","

    I don't understand I'm afraid. Where is name2 on your page? And do you mean a select element with multiple=true which combines the selected values to be comma separated?

    Allan

    Sorry, there was a problem with my expression. Now I have output. NAME2 is a dataset separated by, such as Mountainengineering, Fashion, Leisure, Sports. However, what I want to output is that NAME2 is a multi option SELECT with options such as Mountainengineering, Fashion, etc. I don't know where to separate this name2

  • lancwplancwp Posts: 85Questions: 18Answers: 1

    I feel like it needs to be processed in the staff.php

    staff.php ************************************(Part of the code)

    <?php
    
            Field::inst( 'ocorder.type2' )
        ->options( Options::inst()
          ->table( 'serviceshow4' )
            ->value( 'name' )
         ->label( 'name' )
               ),  
       ......                                                                           
           Field::inst( 'serviceshow4.name2' ),      
    
          ->leftJoin( 'serviceshow4',   'ocorder.type2',   '=', 'serviceshow4.name' )
          ->where ( 'serviceshow4.removed_date', null )    
           ->where( 'ocorder.removed_date', null )
    
    
    ...?>
    

    The problem seems to be in this position
    Field::inst( 'serviceshow4.name2' ),

    Datasets with ',' signs are not separated here

  • allanallan Posts: 61,972Questions: 1Answers: 10,160 Site admin

    Right - so the value stored in ocorder.type2 is a string with a comma separated list of values? If that is the case use the separator and multiple option of select - e.g.:

    multiple: true,
    separator: ',',
    

    Allan

  • lancwplancwp Posts: 85Questions: 18Answers: 1

    yes, the value stored in is a string with a comma separated list of values ,It is for this field TYPE3 (serviceshow4.name2),The value of TYPE2 is correct and does not need to be separated

  • allanallan Posts: 61,972Questions: 1Answers: 10,160 Site admin

    Okay - thanks. Is this now resolved, or do you have a further question on it?

    Allan

    Thank you for your continuous response. What I want to achieve is:

    When the first red arrow corresponds to a dropdown selection of a column, the second red arrow should also be able to drop down. The dropdown items of this column are the values separated by "," here,

    I don't know how to modify Field:: inst ('serviceshow4. name2 ') in order to achieve such a dropdown

  • allanallan Posts: 61,972Questions: 1Answers: 10,160 Site admin

    Should the options of the second select change based on the value selected in the first? If so, see this blog post.

    If you have two select elements dependent on each other, I would also strongly suggestion you show them both as editable at the same time. See this example for how to trigger inline editing on multiple cells at the same time.

    Thank you for your continuous response
    Please check the latest URL
    http://www.oceanshoes.com/temp/gborder.php

    The latest countries2.php code is as follows

    <?php
    // DataTables PHP library
    include( "../lib/DataTables.php" );
    $values = $_REQUEST['values']['ocorder.type2'];
    
    //print_r($_REQUEST);
    //echo json_encode(array());
    
    if (! $values) {    
        echo json_encode(array() );
    
        return;
    }
    $countries = $db
        ->select( 'serviceshow4', array('name2 as value', 'name2 as label'),array('name' => $_REQUEST['values']['ocorder.type2']))
    
    
    
        ->fetchAll();
    
    echo json_encode( array(
        'options' => array(
            'ocorder.type3' => $countries
        )
    ) );
    ?>
    

    The secondary linkage is ready, they are working very well, and now there is only one problem left. The value of the secondary linkage is a string separated by "," ,such as "Baotou, Fashion, Fashion, Leisure, Sports", but I want these values to be separated by "," and "options. How can I modify them to achieve this?

  • allanallan Posts: 61,972Questions: 1Answers: 10,160 Site admin

    For your column 分类 there is only ever one option shown in the select.

    Even if we were to split the value by comma, I don't understand where the options for that list should come from? How can there only be a single option for it, and that option is always selected. It seems like you need to resolve the list of options as the first priority. Unless I'm totally misunderstanding.

    Allan

  • lancwplancwp Posts: 85Questions: 18Answers: 1

    The separated list option is itself, which means separating its own fields into different list options through ","

    It's already done, all the issues have been resolved. Thank you all
