This piece of code gets all the form variables and sends them via AJAX to the PHP script. But I want the calculated results from the PHP script that is being returned to the javascript via a JSON encoded array to be in the form of "post":{"uname":"someNamefromForm","email":"someEmail","fname":"namefromtheform","lname":"lastnamefromform" }... The output I'm getting now is "uname=e&email=e&fname=e&lname=euname".. This is the JSON array I want to displayed at the bottom of the page for debugging purposes. Can someone tell me how to format it please
This is my HTML form
<div id="wrapper">
<h2> Validation with AJAX,JQuery,JSON and PHP</h2>
<div class="form-container">
<span id="ajax-message"></span>
<form id="ajax-form" onsubmit="return false;">
<p class="legend">All fields marked with an asterisk are required.</p>
<fieldset>
<legend>User Details</legend>
<div>
<label for="uname">Username <em>*</em></label>
<input id="uname" type="text" name="uname" value="" />
</div>
<div>
<label for="email">Email Address <em>*</em></label>
<input id="email" type="text" name="email" value="" />
</div>
<div>
<label for="fname" class="error">First Name <em>*</em></label>
<input id="fname" type="text" name="fname" value="" size="50" class="error"/>
<p class='note'>All error message go here </p>
</div>
<div>
<label for="lname">Last Name <em>*</em></label>
<input id="lname" type="text" name="lname" value="" size="50" />
</div>
</fieldset>
<div class="buttonrow">
<input type="submit" value="Submit This Form via AJAX" class="button" />
<input type="button" value="Start Again" class="button" />
<a >Refresh this Page</a>
</div>
</form>
</div>
<h3>JSON Array</h3>
<pre id='debug'></pre>
</div>
This is my javascript
$("#ajax-form").submit(function(){
var variableToSend = $(this).serialize();
$.post(
'ajaxformval_post.php',
{variable: variableToSend},
function(data){$("#debug").html(data)},
"json"
);
})
This is the php
<?php
$variable = $_POST['variable'];
echo json_encode($variable);
/*$json = array(
'booleanFlag' => TRUE,
'someText' => "AJAX should be renamed AJAJ",
'anArrayOfData' => array('name' => 'Mickey', 'ears' => 'very Big')
);*/
?>
You can send your serialized variable directly like this:
$("#ajax-form").submit(function(){
var variableToSend = $(this).serialize();
$.post(
'ajaxformval_post.php',
variableToSend,
function(data){$("#debug").html(data)},
"json"
);
});
Then on the server side simply output the json_encoded post:
<?php
$variable = $_POST;
echo json_encode($variable);
?>
Did you try changing the "json"-parameter from the $.post-method?
According to documentation https://api.jquery.com/jQuery.post/
dataType
Type: String
The type of data expected from the server. Default: Intelligent Guess (xml, json, script, text, html).
So I guess if you give him "json" he will automatically decode the returned data.
