I am attempting to create a custom abide validator to check if the username already exists. Everything I find online including here is for foundation 5 and the structure is completely different.
Foundation.Abide.defaults.validators['checkUser'] =
function($el,required,parent) {
console.log('checking');
$.post( "func/checkUsername.php",{'user':$el.val()}, function( data ) {
if(data.status==1){return true;}
else{return false;}
console.log('complete');
});
};
This is my input field
<input type="text" id="usrnme" name="usrnme" required pattern="checkUser" value="" />
No matter what I do it will not submit to the console and it always comes up invalid.
pattern="checkUser" change to data-validator="checkUser"
<input type="text" id="usrnme" name="usrnme" required data-validator="checkUser" value="" />

I'd like to validate a form with ajax where there is a checkbox field.
I tried in this way but I can't get the value of checkbox field.
MY FORM
<form class="Form" action="?">
<input type="text" name="type" id="type" />
<input type="text" name="action" id="action" />
<input type="checkbox" name="chk" id="chk" value="1">
<input type="submit" value="INSERT" />
</form>
MY AJAX
$(".Form").submit(function( event ) {
event.preventDefault();
$.post("control.php", {
type: $("#type").val(),
action: $("#action").val(),
chk: $("#chk").val()
},
function(data){
$("#msg").html(data);
}
});
CONTROL.PHP
// CHECKBOX VALUE
if($_POST["chk"] == 1){
echo "THE VALUE IS 1";
exit;
}
How I could Do this? Thanks
EDIT
I tried pass to control page the chk with no success
$.post("control.php", {
type: $("#type").val(),
action: $("#action").val(),
chk: $("#chk").prop('checked')
},
and
$.post("control.php", {
type: $("#type").val(),
action: $("#action").val(),
$("#chk").prop('checked')
},
How can I define the name of my checkbox field in ajax post? thanks
This returns true if the checkbox is checked:
$("#chk").prop('checked')
And in PHP check it like this:
if(isset($_POST["chk"])) // true
For check boxes, php passing value if only check box selected. so you can check is that check box received to PHP page. if its received user has selected it or if user not selected, no check box name passing to PHP page.
so you can check
if(isset($_POST["chk"]))
...
if this returns true, that means user selected check box and if not user not selected...
One solution is you send a zero value with the same name in a hidden input
<input type="hidden" name="chk" value="0">
<input type="checkbox" name="chk" id="chk" value="1">
and if chk is checked the hidden input chk will be overriden in the $_POST
I want to improve my website and figured out a good way to do it was by submitting forms via AJAX. But, I have so many forms that it would be inpractical to do $('#formx').submit(). I was wondering if there was a way to do this automatically by making an universal markup like;
<form class="ajax_form" meta-submit="ajax/pagename.php">
<input type="text" name="inputx" value="x_value">
<input type="text" name="inputy" value="y_value">
</form>
And have this submit to ajax/pagename.php, where it automatically includes inputx and inputy?
This would not only save me a lot of time but also a lot of lines of code to be written.
First question so I hope it's not a stupid one :)
Something like this should work for all forms. It uses jQuery - is this available in your project? This specific code chunk hasn't been tested per say, but I use this method all the time. It is a wonderful time saver. Notice I changed meta-submit to data-submit so that its value can be fetched using $('.elemenet_class').data('submit');
HTML
<!-- NOTE: All Form items must have a unique 'name' attribute -->
<form action="javascript:void(0);" class="ajax_form" data-submit="ajax/pagename.php">
<input type="text" name="inputx" value="x_value">
<input type="text" name="inputy" value="y_value">
<input type="submit" value="go" />
</form>
JavaScript
$('.ajax_form').submit(function(e){
var path = $(this).attr('data-submit'); //Path to Action
var data = $(this).serialize(); //Form Data
$.post(path, {data:data}, function(obj){
});
return false;
})
PHP
//DEBUGGING CODE
//var_dump($_POST);
//die(null);
$data = $_POST['data'];
$inputx = $data['inputx'];
$inputy = $data['inputy'];
you can create ajax fot text boxes so that it can update to database whenever change the focus from it.
<form id="ajax_form1">
<fieldset>
<input type="text" id="inputx" value="x_value" />
<input type="text" id="inputy" value="y_value" />
</fieldset>
</form>
<script>
$(document).ready(function()
{
$("form#ajax_form1").find(":input").change(function()
{
var field_name=$(this).attr("id");
var field_val=$(this).val();
var params ={ param1:field_name, param2:field_val };
$.ajax({ url: "ajax/pagename.php",
dataType: "json",
data: params,
success: setResult
});
});
});
</script>
I'm building a ajax based shopping cart with Codeigniter, and the add / remove functions work perfectly. I am now trying to add an option for adding multiple items, and can't get it to work.
Here's the markup I'm using. I'm not sure if it's the best design, but it's working with the non-ajax function, so I guess it should be fine.
<form action="cart/add_multiple" method="post" accept-charset="utf-8">
<input type="hidden" name="items[0][id]" value="3571310" />
<input type="hidden" name="items[0][qty]" value="1" />
<input type="hidden" name="items[0][price]" value="59.00" />
<input type="hidden" name="items[0][name]" value="London" />
<input type="hidden" name="items[0][heb_name]" value="לונדון" />
<input type="hidden" name="items[0][full_price]" value="59.00" />
<input type="hidden" name="items[0][discount_price]" value="59.00" />
<input type="hidden" name="items[1][id]" value="7397903" />
<input type="hidden" name="items[1][qty]" value="1" />
<input type="hidden" name="items[1][price]" value="29.00" />
<input type="hidden" name="items[1][name]" value="London Triple" />
<input type="hidden" name="items[1][heb_name]" value="לונדון טריפל" />
<input type="hidden" name="items[1][full_price]" value="29.00" />
<input type="hidden" name="items[1][discount_price]" value="29.00" />
<input type="submit" name="add_multi" value="add to cart" /></form>
The ajax script is as follows:
$(document).ready(function() {
$(document).on("submit", "div#winning_combo_small form", function () { //catches every click on the submit button of the "add to cart" form
var items = $(this).serialize();
alert(items);
$.post(base_url + "cart/add_multiple", {items: items, ajax: '1' },
function(data){
if (data =='true')
{ // Interact with returned data
$.get(base_url + "cart", function(cart){ // Get the contents of the url cart/show_cart
$("#cart_sidebar").html(cart);
})
$.get(base_url + "cart/count_items", function(items){
$("#cart_items").html(items);
})
}
});
return false;
})
});
But it's not working, because the add_multiple function receives the data as a string, not an array. Do I have to decode the data somehow to convert it to an array? Do the Hebrew characters get in the way and mess it all up?
I should say that when posting the form the regular way, without ajax, the items are added to the cart and all works well. So what is the difference between the regular post and the ajax post?
Well, I got it to work, though I'm not sure if it's the most elegant way.
Here's what I did:
In the ajax script, I changed var items = $(this).serialize(); to var items = $(this).serializeArray();. I now get an array instead of a string, but it's not the format I need to insert into the cart. So I looped over this array to create an array in the desired format, and used that new array to insert into the cart.
This is my add_multiple function under the cart controller:
function add_multiple()
{
$items = $this->input->post('items');
$ajax = $this->input->post('ajax');
// Check if user has javascript enabled
if($ajax != '1'){
$this->cart->insert($items); //if posted the regular non-ajax way, the fields will be in an array in the correct format
echo 'false';
redirect('cart'); // If javascript is not enabled, reload the page with new data
}else{
$i = 0;
foreach($items as $key=>$form_field)
{
$field_name = $form_field['name'];
$from_char = strrpos($field_name, '[') +1 ;
$length = strlen($field_name)-$from_char-1;
$field = substr($field_name,$from_char,$length);
$data[$i][$field] = $form_field['value'];
if ($field == "discount_price") $i+=1; // I know 'discount price' is always the last field
}
$this->cart->insert($data);
echo 'true'; // If javascript is enabled, return true, so the cart gets updated
}
}
I am using ASP.net for a program with a number of check boxes and a submit button which initiates an action depending on the selected check boxes.
However, one of my check boxes should behave as this submit button, i.e, upon selecting/deselecting this check box, the same action as the button must be triggered. Can someone please help me in doing this (or perhaps direct me to a tutorial)
I have a controller class and model.
Thanks you
EDIT
The program look like:
#using(Html.BeginForm("controllername", FormMethod.Get)) {
#html.CheckBox("check1");
#HTMl.Checkbos("check2");
<input type="submit" value="Submit" />
}
Everything else is pretty much handled in the controller.
You can use javascript to listen to the check event of your check box and then invoke the form submit.
Assuming your markup of view is like this
<form id="yourFormId" action="user/post">
<input type="checkbox" class="optionChk" value="1" /> One
<input type="checkbox" class="optionChk" value="2" /> Two
<input type="checkbox" class="optionChk" value="3" /> Three
</form>
<script type="text/javascript">
$(function(){
$(".optionChk").click(function(){
var item=$(this);
if(item.val()=="2") //check your condition here
{
item.closest("form").submit();
}
});
});
</script>
EDIT : As per the question edit.
Change the CheckBox Helper method usage like the below to add a css class to the checkbox so that we can use that for the jQuery selection.
#Html.CheckBox("check1",new { #class="optionChk"})
imagining you have something like this:
#using(Html.BeginForm()) {
<label class="checkbox">
<input type="checkbox" name="chb_a" id="chb_a"> Option A
</label>
<label class="checkbox">
<input type="checkbox" name="chb_b" id="chb_b"> Option B
</label>
<label class="checkbox">
<input type="checkbox" name="chb_c" id="chb_c"> Option C
</label>
<label class="checkbox">
<input type="checkbox" name="chb_d" id="chb_d"> Option D
</label>
<button type="submit" class="btn">Submit</button>
}
you can write a simple jQuery to complement:
$(".submit").click(function() {
// find the <form> the element belongs and submit it
$(this).closest('form').submit();
});
and with this, all you need is to add a class named submit to any checkbox or more buttons if you want them to submit
for example:
<label class="checkbox">
<input type="checkbox" name="chb_e" id="chb_e" class="submit"> Option E
</label>
You can bind the click events on the checkboxes.
$( '.myCheckboxes' ).click(function () {
var clickedBox = $( this );
// now do something based on the clicked box...
});
If you need to know which checkboxes are checked, that's just another selector.
$( '.myCheckboxes:checked' ).each(function () {
// Now you have access to each checked box.
// Maybe you want to grab their values.
});
Just bind the checkbox to a click event. Assuming you have a way of uniquely identifying the checkbox that submits the form.
$( '#formSubmitCheckbox' ).click(function() {
$( '#myForm' ).submit();
});
I am using jquery.validate 1.9 and wish to execute code every time the form automatically validates (using the default behavior).
I hoped there would exist an OnValidated event I could hook into, but can not find one.
After validation executes I wish to conditionally enable other parts of the page if the form is valid, and disable otherwise.
How would one go about adding a method call following the existing validate() function?
I'm using jquery validate 1.8.1, but you should still be able to accomplish this using the valid() function.
valid() will either validate the entire form if you pass it the form ID or individual fields if you pass their respective ID's. It will then return a Boolean based on if they are all valid or not.
Something like this should work:
<script type="text/javascript">
function tab1Validation(){
if($('#field1, #field2, #field3').valid()){
//Logic if all fields valid - eg: $('#NextTab').show();
}else{
//Logic if one or more is invalid
}
}
</script>
<form id="yourform">
<div>
<input type="text" id="field1" name="field1" />
<input type="text" id="field2" name="field2" />
<input type="text" id="field3" name="field3" />
</div>
<input name="nextTab" type="button" value="Next Tab" onClick="tab1Validation();" />
</form>
