How to get value from checkbox or radio button immediately after clicking on it and write it in textfield without using reset or submit button?

<input type="checkbox" name="age" value="21-29">21-29 <input type="text" name="yourAge" value="">

    You'll want a javascript event to do that, not php – Darren H Sep 13 '15 at 07:20

You can do like this with jQuery click function More Detail Here

<input type="checkbox" name="age" value="21-29" id="age">21-29
<input type="text" name="yourAge" value="" id="yourAge">

JQuery

$("#age").click(function () {
    $("#yourAge").val($("#age").val());

});

@Shehary is on point but there is always room for more.

JS

<script>       
 var changeInput = function  (val){
            var input = document.getElementById("age");
            input.value = val;
        }
</script>

HTML

    <input type="checkbox" name="age" value="21-29" onclick='changeInput(this.value);' >21-29
    <input type="text" name="yourAge" value="" id="age">

  • Thanks, but you are using JS. I need the code only in PHP. My teacher told me to do it just with PHP. – StykPohlavsson Sep 13 '15 at 12:09
  • @StykPohlavsson Err, no. you'll need to use either JS/jQuery or an AJAX call to POST request back to the PHP on the server. It can't be done in PHP only since PHP is a server-side scripting language. – DirtyBit Sep 13 '15 at 12:15

    @StykPohlavsson either your teacher needs to go back to school to learn the difference between server-side and client-side language or you miss understood what your teacher told you. `get value from checkbox or radio button immediately after clicking on it` there is no possible way without jQuery, Ajax or java-script because then you were asking `without using reset or submit button` – Shehary Sep 13 '15 at 13:33

I know this is old, and my code may not be great, but I like to use this.

<?php
    $get= "?checked";
    $checked= "";
    if(isset($_GET['checked'])){
        $get= "";
        $checked= "checked";
    } 
?>
<a href="waiting_in_db.php<?=$get?>">
    <input type="checkbox" <?=$checked?> >
</a>

But I prefer using CSS and links without the checkbox.
