so I am new to using JQuery and more so .post and what I want to know is:
PHP allows me to post an array of multiple form input values like so:
<input type="text" name="array[]" />
so can I do the same with JQuery post? if so, what is the syntax?
my current use of it has been like so:
$.post('search_item.php', { unit: form.unit.value }...
many thanks,
yes !
$.post("test.php", { 'choices[]': ["Jon", "Susan"] });
answer to comment
one way would be to map them
var choices = $('input[name="choices[]"]').map(function() {
return this.value;
}).get();
// then post would look like
$.post("test.php", { 'choices[]':choices });
Probably the easiest way to do it is something like this:
$.post('file.php',$('input[name=array[]]').serialize(),...
Here's an example that checks for a valid email but it gives you the basic idea: http://www.jensbits.com/2009/10/04/jquery-ajax-and-jquery-post-form-submit-examples-with-php/
$(function(){
$("#JqPostForm").submit(function(){
$.post("process_form.php", $("#JqPostForm").serialize(),
function(data){
if(data.email_check == 'invalid'){
$("#message_post").html("<div class='errorMessage'>Sorry " + data.name + ", " + data.email + " is NOT a valid e-mail address. Try again.</div>");
} else {
$("#message_post").html("<div class='successMessage'>" + data.email + " is a valid e-mail address. Thank you, " + data.name + ".</div>");
}
}, "json");
return false;
});
});
The id of the form in the example above is #JqPostForm. The serialize function puts all the form fields in the PHP $_POST object and you can grab them on the process_form.php page (or whatever page you are using for form processing) just as if the form was submitted to that page. For example, $_POST['email']
.post is a shorthand Ajax function
