Text field php writing method

In this example, we create a simple form that contains a text field and a submit button . The form's action attribute points to a PHP file named process.php, which is used to process form submission data. The form's method attribute is set to post, which means the form data will be submitted to the $_POST super in the process.php file in the global array.

In the process.php file, we use the if statement to check whether the requested method is post. If so, the text field The value of is stored in the $message variable. Next, we use echo to output this variable so that the user can see their entered message on the page.

In short, using text fields in PHP is similar to other form controls. You need to set the text area using the </code> tag in HTML and use the <code>$_POST</code> or <code>$_GET</code> superglobal variable to get the form submission data. If you implement appropriate validation and filtering in your form processing code (such as removing text containing malicious scripts), a text field can be a powerful form input control. </p><p>The above is the detailed content of Text field php writing method.
