cómo pasar el valor <entrada> a php usando carga ajax

I am trying to pass a value of an input item to php when loading the php file using ajax_load. this is that I have so far but it's not working.

html and jquery:

<tr>
    <td></td>
    <td>
        <button class="grey">Test Settings</button></td>
</tr>

<tr>
    <td></td>
    <td><div class="font-size-15 color-semi-black" id="result"></div></td>
</tr>
<input type="hidden" name="control" value="1"/>

<!--Test Settings-->
{literal}
    <script>
        $.ajaxSetup({
            cache: false
        });
        var ajax_load = "<img src='images/loaders/small-loader.gif' alt='loading...' />";
        var value = $("input[name='control']").val();
        //  load() functions
        var loadUrl = "demo/test_settings.php?val=" + value;
        $("button").click(function() {
            $("#result").html(ajax_load).load(loadUrl);
        });

    </script>
{/literal}

php

if ($val == '1'){

//process code here. 

}

It's not passing the value of the input. any suggestions?

No need to. He can capture it trough query string -

there are numbers of ajax jquery tutorials. try to search in Google -

it would be very helpful if you could just post the actual content of your test_settings.php file too. Otherwise, we assume that your $val is set as: $val = $_GET['val']. -

thank you all for commenting. the reason I did not post the content of the php is because it is about 200 lines of coding which is not related to this. but same suggestion as below works great. -

your request is going with GET como esto:-

/demo/test_settings.php?val=1&_=1401278450924

so you need to get your values by $_GET on test_settings.php como

if ($_GET['val'] == '1'){

thank you for your suggestion. had a few problem with ?val=1&_=1401278450924 but I changed to .php?val=1"; and that works - user3620142

En su $.load pass data to it as a parameter.

$("button").click(function(){
    $("#result").html(ajax_load).load(loadUrl , {
         val : ...
    });
});

En su archivo php:

if (isset($_REQUEST["val"]) && $_REQUEST["val"] == 1) {
    ...
}

If you pass an object, it is passed as POST, otherwise it is passed as GET.

Y, qué piensas load() ¿lo hace? - aspirina

Edited it. Somehow forgot you can actually pass parameters to load, my bad. - Mareckmareck

This is not the problem, he is already passing the value in the query string. The problem is how he retrieves it in php - Steve

Yeah, but passing the values like that is a better way to deal with it. - Mareckmareck

guys, I was able to use suggestions from here and do this. test_connection.php?val=1"; php: ($_GET['val'] == '1'){ and it works fine - user3620142 

if (count($_GET) && $_GET['val'] == '1'){
}
