Why is my jQuery serialized form not sending data to my PHP script?
Nov 02, 2024 pm 10:25 PMSerializing and Submitting a Form with jQuery and PHP
Problem:
A serialized form using jQuery fails to send data to a PHP script. The server receives no data.
HTML Form:
`
`JavaScript:
<code class="javascript">$("#contactForm").submit(function() { $.post("getcontact.php", $("#contactForm").serialize()) .done(function(data) { // handle response }); return false; });</code>
Server-Side PHP (getcontact.php):
<code class="php">$nume = $_REQUEST["nume"]; // empty $email = $_REQUEST["email"]; // empty $telefon = $_REQUEST["telefon"]; // empty $comentarii = $_REQUEST["comentarii"]; // empty</code>
Solution:
Replace the jQuery.post() code with the following:
<code class="javascript">var datastring = $("#contactForm").serialize(); $.ajax({ type: "POST", // method url: "your url.php", // action data: datastring, // form data dataType: "json", // expected response type success: function(data) { // handle response }, error: function() { // handle error } });</code>
Additional Notes:
- Set dataType to "jsonp" for cross-domain requests.
- Use beforeSend and complete callbacks for pre-request and post-request actions.
- Consider using async: false for synchronous requests.
- Disable caching with cache: false.
- Refer to the official documentation for more details.
Update
- var_dump($_POST) should return an empty array.
- The issue may be server-related, such as a misconfigured PHP.ini file or disabled file uploads.

To merge two PHP arrays and keep unique values, there are two main methods. 1. For index arrays or only deduplication, use array_merge and array_unique combinations: first merge array_merge($array1,$array2) and then use array_unique() to deduplicate them to finally get a new array containing all unique values; 2. For associative arrays and want to retain key-value pairs in the first array, use the operator: $result=$array1 $array2, which will ensure that the keys in the first array will not be overwritten by the second array. These two methods are applicable to different scenarios, depending on whether the key name is retained or only the focus is on

To determine the strength of the password, it is necessary to combine regular and logical processing. The basic requirements include: 1. The length is no less than 8 digits; 2. At least containing lowercase letters, uppercase letters, and numbers; 3. Special character restrictions can be added; in terms of advanced aspects, continuous duplication of characters and incremental/decreasing sequences need to be avoided, which requires PHP function detection; at the same time, blacklists should be introduced to filter common weak passwords such as password and 123456; finally it is recommended to combine the zxcvbn library to improve the evaluation accuracy.

To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

There are three common methods for PHP comment code: 1. Use // or # to block one line of code, and it is recommended to use //; 2. Use /.../ to wrap code blocks with multiple lines, which cannot be nested but can be crossed; 3. Combination skills comments such as using /if(){}/ to control logic blocks, or to improve efficiency with editor shortcut keys, you should pay attention to closing symbols and avoid nesting when using them.

The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.
