How To Update Form Input Field Background Colour On Validation Error
I have been searching for form validation scripts for ages and all th ones that I like are far too complicated and inflexible so I decided to stick with my own which is easier to understand.
The only thing I don't like which i have seen on better form validation scripts is that and fields with errors are highlighted. i can only presume that they have used php to set the background color of the input field or textarea.
How would I add some code to change the background colour of form elements if an error is found? Here is my code which validates the form but doesn't change form elements colours. Code:

Form Field Validation
When validating user input I check it's not empty and then run 'mysql_real_escape_string($s)', I was then going to make sure that it is only alphanumeric, but I wanted to allow certain other characters as well. Realising this must be done before the mysql escape check, what characters should be blocked because they are dangerous, I can only really think of quotes and $. The real escape check should handle the quotes issue, so is the $ an issue or not?

Form Validation :: Check Each Field
I have many forms on my site and so far just check to see if my vars have a value and if not just show a messages saying please fill out such and such a field. What i want to do is, check that each form field has a value and for the ones that dont, send the appropriate error message or number to another script that displays the error messages. This way I have one error page used to display various errors from all forms of my site. So i need a way to send the error messages to the error page. Like an array then i can just iterate the error array to display each message. Why the extra page? Cause i'm using a template that wont be easy to put directly into form processing scripts. It could be done but i would prefer a cleaner method.

PHP Form Field Update...
I am sure this has been answered here somewhere, but I have searched for a good 2-3 hours and can't seem to locate a solution. Additionally, I really don't want anyone to solve this mystery for me (at least not all the way!) - But I was hoping someone could point me in the right direction here. I am trying to figure out how to update form field information before the end user hits the submit button - for example, if they select that they are from California from the "state" drop down list, only counties from California would show up in the "county" drop down list. BTW, this is only a hypothetical example - I am only using this code to build a photo manager for my website! Anyone able to: 1) tell me what this process is called - it's hard to search for answers when you don't know what you're looking for. 2) point me in the right direction of a solution.

Clearing The Input Text Field After Submiting The Form To A New Page
I have a page with a form with an input text field ... and when a user types his/hers ID ... and submits the form - his/hers page opens in a NEW window .... but the value (ID) that was written in the original window remains. I want to make sure that the form input field on the original page becomes "invisible" - by refreshing/reloading the original page or just by clearing the input form after submission. For now I have put in a meta refresh tag in the head of the html file ... but that is not the solution ... becouse I only need a one time refresh/reload of the page ... and this is to happen right after the input text value is being submitted.

Update Form Throws "Undefined Index" Error For Unchecked Radio Button Fields On Form
I have display error ON and error reporting to E_ALL. I have a form that opens fine. When you submit it, all the fields that have nothing in them, for example an un-selected radio button, throw the error similar to that below. Notice: Undefined index: fld_ONECHOICE in /usr/..../updateFORMFACT.php on line 29 These fields are not required for the form to be completed. Do I HAVE to default all fields to yes/no or some entry? Surely not. Is this just something that shows with error reporting set to E_ALL and I shouldn't worry about it?

Input Validation
The idea is to have a way to seperate business rules and validation rules from programming logic and have a shared set of rules for both php and javascript. Here is a code snipet to show you how much time/coding this type of framework could save you. I'm still in the early stages of development and have some issues to work through but this should give you the idea. include_once "xml_rule_validator.php"; $xrv = new XMLRuleValidator(); $xrv->load_from_file("xml_validation_rules.xml"); $valid = $xrv->validate_php(); if( !$valid ) { $xrv->display_error_summary(); } And that's it... it would validate all get/session/post variables as specified in the xml document. So if you want to add or remove a check from a field... you make a simple change to an xml document rather than going in and hunting through lines of code. In my case I've got hundreds and hundreds of lines of code per page down to something like that. So what are your guys thoughts? Do you have different alternatives that you think are better? Any improvements upon my idea?

Input Validation And Multiple Forms
I am using a content management system written in php. the system allows me to use html blocks. in one block I have a zip code store search with javascript input validation plus php server side validation if anything makes it past the client side js. in anotehr block I have another submission form for a sign up with client side javascript validation and php server side validation if anything makes it past the client side. the javascript validations seem to conflict with each other. By that i mean if i click submit on the one form, the other forms client side validation kicks in. is there a way to separate the forms in terms of submitting and validation on the client side javascript ? i fire off client side validations with the 'onSubmit()' function by the way. ALSO, on the zip code entry form I have javascript to prevent them from entering anything but numbers which also conflicts with the other user submissin form. Code:

Field Validation
Flushed with that success, I thought I'd tackle the problem of heavy-handedness on the submit button. Over some 10 days I struggled, without success, with all manner of script solutions and finally ripped all trace of that out. Next attempt I thought of would be to use the header route with Location, taking clients to a new page with an acknowledgement for them but without the form itself. No can do, of course, because I ran into the infamous header redirection problem. At the moment, it seems I have no alternative but to rely on mysql to sort out duplicates. Has anyone come across a solid solution to this.

Spaces In Input Field
I'll give an example of the problem. Someone comes and fills a text field with thier details, like thier address, but they make a mistake and press the space button twice or more between their words. When it echos the words out you cant tell the mistake because the html makes it look 'ok'. But if the input is sent to the database it has spaces between the words. Is there a way to make sure that only one space is kept between the words before it goes in the databse? I dont want it to say error and make the people fill the form again, i want the script to fix the error.
