Validating phone number php
HP 5.3.3 and 5.2.14 had a bug ( related to FILTER_VALIDATE_EMAIL, which resulted in segfault when validating large values.
Simple and safe workaround for this is using strlen() before filter_val().
Any errors or omissions will be highlighted with a message alongside the relevant field. The purpose of the form is to capture user details (name, address, and email) to obtain feedback (on fruit consumption and favorite fruit) and request a brochure.
The name, address, and email fields are text renders the input as a radio button. This is because collectively the radio buttons should be treated as a group (the user should select either 0, or 1, or 2, etc.). Its value is presented as its label, and clicking on it will trigger the form submission.
If the user does not comply with these rules, an error message will be displayed.
Any fields already completed will be left unchanged, allowing the user to simply adjust her input and re-submit the form without having to enter all of the data again. The exception is the brochure checkbox which does not need to be validated as it is an optional field.
In this example, you will need two files as below with correspondence names. These files are commented enough to understand what’s going on. We used text inputs, password inputs, number inputs, radio button inputs and a textarea input. This PHP syntax is shorthand for echoing a variable inline (see this post for more on PHP Shorthand Syntax) and “@” as prefix on any expression in PHP, any error messages that might be generated by that expression will be ignored.
We used “@” in case if the variable is not set, it won’t show any error.
Client side form validation is done in user’s machine but server side form validation is done on server.In the at very beginning, we initialized variable name $error as blank.Then rest of the script will be executed if the form is submitted as line 11.As server side form validation is done on server, the submitted data is validated and cleaned by server and then it is used.No one can modify those data without having access to the server. If you want, you can use get method, just change method=”get” and replace $_POST with $_GET – that’s all.
