One extra note: j Query is used throughout the Java Script files. Pass your DB instance to the validate_input function. That has got to be the largest function I've ever seen!field_var cross = ''; var tick = ''; var loading = ''; // Send the data from the form to the PHP file 'jqueryvalidate.php', where they will call the function to validate the data $('input:text,input:password,input[type=email]').blur(function() ); $('input:checkbox').click(function() ); As you can see, this has two different functions for the validation: one for text, password and email fields and another for checkboxes. You're unnecessarily tying your validate_input function to mysql Connect(). There's no reason to type that My SQL block over and over again.An overview of the files can be seen below: There are two files and two files which we will need to include in our HTML.All other resources such as the Bootstrap framework, j Query, and web fonts will be included externally via CDN.If so, it allows it to be submitted to the server and (usually) saved in a database; if not, it gives you error messages to explain what you've done wrong (provided you've done it right).Form validation can be implemented in a number of different ways.Now we will see how we can validate our entered form data before submitting it to the web server.The following example shows how to validate an entered email address.
Also, if all of your cases return true if nothing is wrong, you can just end the Not to say this works 100%. I'm unclear about the JQuery because I haven't done much with it, but from what I remember it should still work.In the above form, we are calling validate() to validate data when onsubmit event is occurring.The following code shows the implementation of this validate() function.Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button.If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information.
