Question

Hi all,

I have in my js file:

function sendDataToPhp()
{
  theUrl = 'myfile.php';
    params = '';
    params += 'function=sendData';

    params += '&myfield='+someVariableForMyField;
    $.ajax ({
        url: theUrl,
        data: params,
        type: "POST",
        async:false,
        success: function (data, textStatus)
        {    
        }
    }); 

}

Then in myfile.php

if (isset($_REQUEST['function']))
    {
        $function = $_REQUEST['function'];

    }  


    switch ($function) {
        case 'sendData':
        //code
        break;
        default:
       //code
}

With this I’m sending the code flow to the sendData case of the switch.

Now Inside the success, in the ajax() I need to send the code flow to the default case of the switch. How can I do that?

Thanks a million!

The way Switch works is if there isn’t a matching CASE then it goes to DEFAULT case … so perhaps you can provide function=IdontExistFunction in your ajax call … OR if there is piece of code in DEFAULT you want to run then best to separate it and make it a function so that you can call from anywhere as required.

BTW – There is GOTO statement available too – not sure if you can make use of it in your case http://php.net/manual/en/control-structures.goto.php ?
