<div id = "result"> Fade me in and hide div hideme</div>
<div id="hideme">
<form method="POST">
Yes<input type="radio" name="name" value="yes"/>
No<input type="radio" name="name" value="no" checked=true />
<input type="submit" id="submit" name="submit" value="HIDE NOW!" />
</form>
</div>
<script>
$(document).ready(function () {
$('#result').hide();
$('#submit').click(function(e) {
e.preventDefault();
$('#hideme').hide();
$('#result').fadeIn(5000);
});
});
</script>
This will hide my div where the submit is, whenever click on submit it wont send values to PHP.
How to fix that to make it send the values to PHP so i will get the values from html?
You have this e.preventDefault(); in your jquery click handler function. It means that when you press the submit button, the form wouldn't be submitted. It's simply preventing original action of that selector on click.
Here's how to fix it. Use ajax. There's many jquery functions for that, i will show you how to use $.ajax method.
$('#submit').click(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "yourphpscriphere.php",
data: "name=" + $('input[name="name"]').val(),
success: function() {
alert('thank you for using my form');
},
error: function() {
alert('an error happened during the request');
}
});
$('#hideme').hide();
$('#result').fadeIn(5000);
});
Remember to change url to your own. Then you can get your radio button value using $_POST['name'] in php.
try this code :
html:
<div id="result"> Fade me in and hide div hideme</div>
<div id="hideme">
<form method="POST" id="eform">
Yes<input type="radio" name="name" value="yes"/>
No<input type="radio" name="name" value="no" checked=true />
<input type="submit" id="submit" name="submit" value="HIDE NOW!" />
</form>
</div>
jQuery :
$(document).ready(function () {
$('#result').hide();
$('#submit').click(function(e) {
$.post("page.php",$("#eform").serialize(),function(data){
$('#hideme').hide();
$('#result').html(data).fadeIn(5000);
})
});
});

This is my registration form located in login.html:
<form action="Registar.php" method="post">
<input type="text" name="user" placeholder="Username (Sem espaços)" maxlength="25">
<input type="text" placeholder="Email" name="email" maxlength="31"/>
<input type="text" name="nome" placeholder="Nome" maxlength="31"/>
<input type="text" name="morada" placeholder="Morada" maxlength="120"/>
<input type="hidden" name="action" value="login">
<input type="number" name="telefone" placeholder="Telefone" maxlength="15"/>
<button type="submit" class="btn btn-default" name="submit">Signup</button>
</form>
It goes to "Registar.php" and runs the verification's i want like if the fields are empty or if the username already exists and show's that verification's in a jquery dialog.
Heres my Jquery script:
function alerta(msg,link){
var dialog = $('<div>'+msg+'</div>');
$(function() {
$( dialog ).dialog({
modal: true,
buttons: {
Ok: function() {
window.location = link;
}
}
});
})
};
The thing is it shows the dialog on the blank page of "Registar.php" and since i scripted some nice styles and overlays for my jquery dialog i want to show the jquery dialog verification messages in login.html and have that page in the background/overlay of the dialog.
Is there any way to do that but still running the action form to an external php script?
Thanks in advance!
One way to achieve this would be to use AJAX instead of sending the form via POST. Here's an example:
HTML
<form id="myForm" action="" method="post">
//your form content
</form>
JQuery
$('#myForm').on('submit', function(e) {
e.preventDefault(); //stop form submission
var formData = $(this).serialize();
$.ajax({
type: "POST",
url: "Registar.php",
data: formData,
success: function(result) {
//result is the value returned from Registrar.php
console.log(result);
//show the modal
}
});
});

I've been having this issue for a while now and I guess I'm stuck. I've been reading on how to use AJAX to send data to a PHP file.
The thing is, I don't really get how to take the value of a radio button in a HTML page and then send that value through AJAX to a PHP file which will then process that value.
So for example:
If I had 2 radio buttons
<input type="radio" name="radio" value="yes">
<input type="radio" name="radio" value="no">
And I would like to take the value of those radio buttons and send it to my PHP file using AJAX.
Next I would be able to process those values in PHP.
How would I make it so that AJAX sends the value of the selected radio button to PHP?
Thanks, in advance!
EDIT:
Full code:
HTML File
<script type="text/javascript">
function updatePremium() {
var input1= $("#premium-yes").val();
var input2= $("#premium-no").val();
$.post( "upd_premium.php", { input1: input1, input2: input2 } );
}
</script>
<div class="usersRow2">
<form action="" method="POST"><label>Premium:</label> <p class="text-info-premium"><?php echo ucwords($premium_check) ?><i class="icon-star"></i></p> <div class="controls-premium"><i class="fa fa-pencil"></i> Edit</div></form>
</div>
<script>
$('#edit-premium').click(function() {
var text = $('.text-info-premium').text();
var input = $('<input type="radio" name="premium" id="premium-yes" value="yes">Yes <input type="radio" name="premium" id="premium-no" value="no">No <div id="premium"></div>')
$('.text-info-premium').text('').append(input);
$('#edit-premium').remove();
$('Update').insertAfter('#premium');
$('<i class="fa fa-times" title="Cancel Edit"></i> <br /><br /><br />').insertAfter('#update-premium');
$('.fa-times').click(function() {
location.reload();
});
});
</script>
PHP File
if($_POST['input1'] == 'yes') {
print_r($_POST);
}
Use jQuery. From the docs, a post is easy:
$.post( "test.php", { name: "John", time: "2pm" } );
Now, you need to get the values of the inputs and pass them to the post:
<input type="radio" name="radio" value="yes" id="input1">
<input type="radio" name="radio" value="no" id="input2">
<script>
var input1= $( "#input1" ).val();
var input2= $( "#input2" ).val();
$.post( "yourphpfile.php", { input1: input1, input2: input2 } );
</script>
I'm trying to create a search feature that searches a database based on the criteria a user has entered. Right now, I'm just trying to get the jQuery variable data into PHP. I've decided to use the shorthand AJAX $.post method because this is just a demo project. I know there are numerous similar questions like mine, but I have yet to find an answer to any of them that I can use.
So what I'm trying to do is, the user will click on a drop down menu and select an option. AJAX then sends the selected value to the PHP file and the PHP will eventually perform a database search based on what was selected. The issue is, in PHP, I'm getting a string of "Search" when the data is parsed and I echo it but when I do a console log on the variable that was sent, I'm getting the correct text. Can anyone tell me where I'm going wrong?
Here's what I have so far.
AJAX
$("#search_form").on("submit", function(ev){
ev.preventDefault();
$.post("../php/test.php", $(this).serialize(), function(data){
console.log(data);
})
})
PHP
ob_start();
require("../includes/header.php");
$criteria = $_POST["search"];
ob_clean();
echo $criteria;
HTML
<form id="search_form" method="post">
<fieldset id="search_by">
<div class="select" name="searchBy" id="searchBy">
<p>Search By...</p>
<div class="arrow"></div>
<div class="option-menu">
<div class="option">Airport Identifier</div>
<div class="option">Top Rated</div>
<div class="option">Instructor</div>
<div class="option">Malfunctions/Maneuvers</div>
</div>
</div>
<input type="text" name="search" id="search" />
<input type="submit" class="button" value="Search_Now" />
</fieldset>
As Requested
Here is a fiddle of the drop down menu to show how it works.
http://jsfiddle.net/xvmxc0zo/
Your form is being submitted via default form submission; the ajax call is misplaced, it should be within the submit handler, which should prevent default form submission.
Note that I have removed both name and id attributes from the submit button; you do not need them. Just let the submit button do it's job and listen for the submit event on the form where you would then use event.preventDefault(); to make sure the form does not submit, then you can make your ajax call.
$("#searchBy").on("click", ".option", function(){
$('#search').val( $(this).text() );
});
$('form').on('submit', function(e) {
e.preventDefault();
$.post("../php/test.php", $(this).serialize(), function(data){
//jsonData = window.JSON.parse(data);
console.log( data);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form>
<fieldset id="search_by">
<div class="select" name="searchBy" id="searchBy">
<p>Search By...</p>
<div class="arrow"></div>
<div class="option-menu">
<div class="option">Airport Identifier</div>
<div class="option">Top Rated</div>
<div class="option">Instructor</div>
<div class="option">Malfunctions/Maneuvers</div>
</div>
</div>
<input type="hidden" name="search" id="search" />
<input type="text" name="search_text" id="search_text" />
<input type="submit" class="button" value="Search" />
</fieldset>
</form>
In your PHP use echo $criteria; instead of echo json_encode($criteria);.
I'd suggest to use the way of jQuery documentation to check changes in your drop down.
$( "select" ).change(function () {
$( "select option:selected" ).each(function() {
$.post("../php/test.php", {search: $(this).text()}, function(data){
jsonData = window.JSON.parse(data);
});
});
})
You are getting "Search" on the PHP side because that is the value of your submit button.
You want the post to occur when you click on an option? Try adjusting your selector as follows:
$("#searchBy .option").on("click", function () {
var search = $(this).text().trim();
$.post("../php/test.php", { search: search }, function (data) {
jsonData = window.JSON.parse(data);
})
});
I think your header.php is provoking the error. I created a test file myself with your code and that works perfectly fine:
<?php
if($_POST)
{
ob_start();
//require("../includes/header.php");
$criteria = $_POST["search"];
ob_clean();
echo json_encode($criteria);
exit;
}
?>
<fieldset id="search_by">
<div class="select" name="searchBy" id="searchBy">
<p>Search By...</p>
<div class="arrow"></div>
<div class="option-menu">
<div class="option">Airport Identifier</div>
<div class="option">Top Rated</div>
<div class="option">Instructor</div>
<div class="option">Malfunctions/Maneuvers</div>
</div>
</div>
<input type="text" name="search_text" id="search_text" />
<input type="submit" name="search" id="search" class="button" value="Search" />
</fieldset>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
$("#searchBy").on("click", ".option", function(){
var search = $(this).text();
$.post("<?=$_SERVER['PHP_SELF']?>", {search: search}, function(data){
jsonData = window.JSON.parse(data);
console.log(jsonData); //Prints the correct string
})
});
</script>
Using the jQuery form plugin, I just want to submit the visible fields (not the hidden ones ) of the form.
HTML:
<div class="result"></div>
<form id="myForm" action="comment.php" method="post">
Name: <input type="text" name="name" />
Comment: <textarea name="comment"></textarea>
<div style="display:none;">
<input type="text" value="" name="name_1" />
</div>
<input type="submit" value="Submit Comment" />
</form>
I cannot find a way to submit only the visible fields using any of the methods below:
ajaxForm:
// wait for the DOM to be loaded
$(document).ready(function() {
// bind 'myForm' and provide a simple callback function
$('#myForm').ajaxForm(function() {
alert("Thank you for your comment!");
});
});
ajaxSubmit:
$('#myForm').ajaxSubmit({
target: '.result',
success: function(response) {
alert("Thank you for your comment!");
}
});
There is another method formSerialize but found no way to use it with the 2 methods mentioned above (usable with $.ajax however).
How to submit only the visible fields using any of the two methods ?
$("#myForm").on("submit", function() {
var visibleData = $('#myForm input:visible,textarea:visible,select:visible').fieldSerialize();
$.post(this.action, visibleData, function(result) {
alert('Thank you for your comment!');
});
// this is needed to prevent a non-ajax submit
return false;
});
I have a form for Tags that is working OK, with some server validation, I would like to add a Jquery to submit the content without refreshing:
<form method="post" action="tags">
<div>
<input type="hidden" name="id" value="getId()" />
<input type="text" name="tag" />
<input type="submit" value="Add" name="add" />
</div>
</form>
Any advice will be highly appreciated.
Check out the jQuery Form Plugin. Using it, you can submit a form without reloading the page like so:
<form id="aForm" action="target.php" method="post>
...
</form>
<script type="text/javascript">
$(document).ready(function() {
$("#aForm").ajaxForm();
});
</script>
The ajaxForm() function also supports all options (such as a callback function) that can be passed to the standard jQuery $.ajax function.
$(document).ready(function() {
$(form).submit( function() { // could use $(#submit).on('click', function(){ as well
$.ajax({
url: 'yourposturl',
data: $(form).serialize(),
Success: function() {
alert('ok');
}
}); //end ajax
return false;
}); //end submit()
});
Should take all form vars , serialize them so the server can receive, the return false is so page doesnt refresh on submit (stops propagation and default)
Add the JQuery javascript library
Turn the submit into a button
<button id="submitbutton" >Add</button>
Add ids to your inputs
<input type="text" id="tag" name="tag" />
And add the jquery to the click for the button ...
<script type="text/javascript">
$(document).ready(function() {
$("#submitbutton").button().click(function(){
$.post("tags.php",{id: $("#id").val(), tag: $("#tag").val()});
});
});
</script>
<form method="post" action="tags">
<div>
<input type="hidden" name="id" value="getId()" />
<input type="text" name="tag" />
<input class="button" type="button" value="Add" name="add" />
</div>
</form>
$(function(){
$('.button').click(function(){
var data = $('form').serializeToObject();
$.post('tags.php', data);
});
});
// jQuery Extension to serialize a selector's elements to an object
$.fn.serializeToObject = function () {
var o = {};
var a = this.serializeArray();
$.each(a, function () {
if (o[this.name] !== undefined) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
