Heres my suggestion for you. Hopefully this makes sense and works for you. Please try to understand what is happening rather than just copy and hope it works. Your form, on submit, gets sent to the JS file. This grabs the form values, uses JSON to send them to your php file which processes everything and returns a response, either true or false. If false, the js file will display your errors on screen and add classes etc. If true you can get it to redirector do whatever you want. <\/p>\n

HTML form…<\/p>\n

<h1>Login<\/h1>\n        <p id=\"results\"><\/p>    \n<form action=\"login_ajax.php\" method=\"post\" id=\"login\" onsubmit=\"jsquicksub(this); return false;>\n                <p id=\"emailP\">Email Address: <input type=\"text\" name=\"email\" id=\"email\" \/><span class=\"errorMessage\" id=\"emailError\">Please enter your email address!<\/span><\/p>\n                <p id=\"passwordP\">Password: <input type=\"password\" name=\"password\" id=\"password\" \/><span class=\"errorMessage\" id=\"passwordError\">Please enter your password!<\/span><\/p>\n                <p><input type=\"submit\" name=\"submit\" value=\"Login!\" \/><\/p>\n    <\/form>\n<\/code><\/pre>\n
In your login.js<\/p>\n
\/\/ hide the div where the error reporting gets displayed on load of the page\n$(document).ready(function() {\n    $('#results').hide();\n});    \n\nvar gb_ajaxbusy = false;\n\nfunction jsquicksub(po_form) {\n\n    if (gb_ajaxbusy)\n        return false;\n\n    gb_ajaxbusy = true;\n\n\n    var lo_request = {};\n    \/\/ go through each and every form element and assign to variable\n    lo_request.e = $(po_form).find('#email').val();\n    lo_request.p = $(po_form).find('#password').val();\n\n    $(po_form).fadeTo(200, 0.3);\n\n    $.getJSON('\/login.php', lo_request, function(po_result) { \/\/ php form processing field\n\n        gb_ajaxbusy = false;\n        $(po_form).fadeTo(0, 1);\n\n        if (!po_result.success) {\n            $('#results').show();\n            document.getElementById('results').innerHTML = po_result.content; \n\n\/\/ inserts errors in specified div. can use alert if wanted\n\/\/ do your thing with adding classes etc if you want to\n            return false;\n        }\n        \/\/ replace form with thankyou message\/redirect somewhere or whatever you want to do\n\n        \/\/ empty results element\n        $('#results').hide();\n\n    });\n\n} \/\/ end jsquicksub()\n<\/code><\/pre>\n
