How to fetch input value with "username" class and send with ajax jquery to php page.
i want to recive data like simple array or simple json. (i need INPUT values and not ids)
var inputValues = [];
$('input.username').each(function() { inputValues.push($(this).val()); });
// Do whatever you want with the inputValues array
I find it best to use jQuery's built in serialize method. It sends the form data just like a normal for submit would. You simply give jQuery the id of your form and it takes care of the rest. You can even grab the forms action if you would like.
$.ajax({
url: "test.php",
type: "POST",
data: $("#your-form").serialize(),
success: function(data){
//alert response from server
alert(data);
}
});
var values = new Array();
$('.username').each(function(){
values.push( $(this).val());
});

In my code below I want display $("#searchresults").html(data) this result to other page.
$.ajax({
type: "POST",
url: base_url + 'front/searchresult',
data: data,
success: function(data) {
alert("test");
var val = $("#searchresults").html(data);
window.location.assign("<?php echo base_url()?>front/search/" + val);
}
});
what exactly is in the data variable you receive from your post? is it a json object? is it plain text?
if it is html, I think you should consider placing the result in a div on the current page, and hide items you don't want to see after searching
relocating after ajax requests is not the way to go. Is it an option in your case, to use a form and change the action attribute of the form to your new location?
<form action="front/search/">
<input type="text" name="data">
</form>
I'm developing a PHP+jQuery application. I'm quite noob with PHP.
Anyway, I'm trying to send a serialized form to a PHP page that will store data to session, via jQuery.
This is a dynamic form, where I could have many input like this:
<input type="text" name="name[]" />
And this is an example of my serialized form:
name[]=name1&name[]=name2
I've tried to get the array with $_POST["name"] from the PHP page, but it did not work.
How can I get this array from the PHP page?
Are you doing something like this???
$(function() {
$('.submit').click(function() {
var names = $('input[name="name[]"]').map(function(){
return this.value;
}).get();
$.ajax({
type: 'POST',
url: url,//this should link to your page
data: {
'name[]': names,
// other data
},
success: function() {
}
});
});
});
</script>
I am trying to write a code that 'stores items for later' - a button that has url of the item as hidden input, on submit it calls a php script that does the storage in a db. I am more into php, very little knowledge of anything object-oriented, but I need to use jquery to call the php script without moving over there
The problem is how to assign the x and y variables when I have multiple forms on one page
I was only able to write the following
$("form").bind('submit',function(e){
e.preventDefault();
var x = $("input[type=hidden][name=hidden_url]").val();
var y = $("input[type=hidden][name=hidden_title]").val();
$.ajax({
url: 'save_storage.php?url='+x+'&tit='+y,
success: function() {
alert( "Stored!");
location.reload();
}
});
});
It works fine if you have something like...
<form method="post" action="#">
<input type="hidden" id="hidden_url" name="hidden_url" value="<?php echo $sch_link; ?>"/>
<input type="hidden" id="hidden_title" name="hidden_title" value="<?php echo $sch_tit; ?>"/>
<input type="submit" id="send-btn" class="store" value="Store" />
</form>
..once on the page, I've got about 50 of them.
These are generated via for-loop I suppose I could use $i as an identifier then but how do I tell jquery to assign the vars only of the form/submit that was actually clicked?
You'll have to scope finding the hidden fields to look within the current form only. In an event handler, this will refer to the form that was being submitted. This will only find inputs matching the given selector within that form.
$("form").bind('submit',function(e){
e.preventDefault();
var x = $(this).find("input[type=hidden][name=hidden_url]").val();
var y = $(this).find("input[type=hidden][name=hidden_title]").val();
$.ajax({
url: 'save_storage.php',
data: {
url: x,
tit: y
},
success: function() {
alert( "Stored!");
location.reload();
}
});
});
As #Musa said, it's also better to supply a data key to the $.ajax call to pass your field values.
Inside your form submit handler, you have access to the form element through the this variable. You can use this to give your selector some context when searching for the appropriate inputs to pass through to your AJAX data.
This is how:
$("form").bind('submit',function(e) {
e.preventDefault();
// good practice to store your $(this) object
var $this = $(this);
// you don't need to make your selector any more specific than it needs to be
var x = $this.find('input[name=hidden_url]').val();
var y = $this.find('input[name=hidden_title]').val();
$.ajax({
url: 'save_storage.php',
data: {url:x, tit: y},
success: function() {
alert( "Stored!");
location.reload();
}
});
});
Also, IDs need to be unique per page so remove your id attribute from your inputs.
I am trying to send some dynamically created input field values to PHP to validate them and make some checks in the database in the background. I don't want to use submit form but just check the fields after click a button.
Html:
<input name="clockpick" class="input-mini timeinputfrom" data-format="hh:mm" type="text"></input>
<input name="clockpick" class="input-mini timeinputfrom" data-format="hh:mm" type="text"></input>
<button id="check" class="btn btn-primary">check</button></div>
The input boxes can be dynamically created depending how many are necessary. I get the values into jquery but don't find any possibility to send them via post to php.
Jquery:
$('#submit').on('click', function() {
var inputfield = $('input[name="clockpick"]');
$('input[name="clockpick1"]').each(function( index, element ) {
console.log( "Wert" + index + ": " + $( element ).val() );
});
$.ajax({
type: "POST",
url: "productiontimevalidate.php",
data: ????
});
How can I send the values / array to PHP?
Another way would be to add the values to an array, and convert it to json for sending.
var allClockPicks = [];
$('input[name="clockpick1"]').each(function( index, element ) {
allClockPicks.push($(element).val());
});
Then, the ajax can send data as
data: {cp: JSON.stringify(allClockPicks)}
On the php side, you can json_decode them as below:
$cpArray = json_decode($_POST['cp'], true);
If your elements are inside <form class="my-form"> [elements...] </form>
You can use this short version:
<script>
$.post('/my/path/app.php', $('.my-form').serialize(), function(r) {
console.log(r);
},'json'); // parse response as JSON
</script>
app.php
<?php
echo json_encode(array('success' => true, 'post', $_POST));
?>
I have a series of Form Elements each with different names, I'll post one as an example. I cannot hard code the name into Jquery because unless I inspect the element, I won't know the name.
With that aside heres the element:
<label class="checkbox">
<input type="checkbox"
name="aisis_options[package_Aisis-Related-Posts-Package-master]"
value="package_Aisis-Related-Posts-Package-master" checked="" />
Aisis-Related-Posts-Package-master
(Disable)
</label>
The catch is to do this:
Grab the name of this element - upon clicking disable - and do two things, one - if the element is checked, which in this case it's not, unchecked it, two pass the name to a php variable, which then can do processing.
How would I do this? Jquery is not my strong area.
Here is a example without knowing more of your code:
$(function () {
$('input:checkbox').click(function () {
$(this).prop('disabled', true);
var iName = this.name;
$.ajax({
url: "file.php",
data: {
'inputname': iName
},
success: function (data) {
alert(data.returned_val);
}
})
})
})
Demo here
If you want to reach the input via name directly you need to use double backslasshes to escape the square brackets and reach that input via name. Use:
$('input[name=aisis_options\\[package_Aisis-Related-Posts-Package-master\\]]')
You can add an onchange with checkbox
onchange="f(this);"
in js f() function you can use this.name to get the name, this.value to get value etc and do whatever you want.
To check/unckeck, you can use $element.prop('checked', true/false); like this (fiddle):
HTML
<input
type="checkbox"
name="aisis_options[package_Aisis-Related-Posts-Package-master]"
value="...."
checked="checked"
/> Aisis-Related-Posts-Package-master
(Disable)
JS
$('.trigger').click (function () {
closest_checkbox = $(this).siblings('input[type=checkbox]');
closest_checkbox.prop('checked', !closest_checkbox.prop('checked'));
});
JS part 2: AJAX
You can build an object with all your name:value combinations using the jQuery plugin serializeObject, your form submission event handler would be something like:
$('form').submit( function (e) {
// Prevent the form from being sent normally since we want it ajaxified
e.preventDefault();
// Send request to php page
$.ajax({
type: "POST",
url: "some.php",
data: $('form').serializeObject() // <== Magic happens here
});
});
PS. Don't forget to include the serializeObject plugin and give a unique id to the form, $('#unique_id') is way better than $('form') which will match all the forms in the page.
To grab the value of name attribute, you can use:
$(this).attr('name');
