Joining Tables with ssp.class.php to Display Parent Names
In this thread, a user encountered an issue where a DataTables plugin for jQuery failed to retrieve parent names from the same MySQL table, where the connection was established through an external column, "father_id."
Solution:
To resolve this, the user must employ either JOINs or sub-queries to fetch parent names from the same table. As ssp.class.php does not inherently support such operations, a workaround is presented.
Implementation:
Within the table definition, a sub-query is utilized to retrieve not only the required columns but also the parent name by associating the "father_id" with the parent's "name" column. The modified code looks like this:
$table = <p>In order for the code to function properly, it is imperative that you remove the backticks from all instances of FROM $table in the ssp.class.php file.</p><p><strong>Additional Notes:</strong></p>
- Ensure that any column names used in the sub-query are unique to avoid conflicts. If necessary, utilize the AS keyword to assign aliases.
- An enhanced version of ssp.class.php, which supports JOINs, can be found at github.com/emran/ssp.
- More details and examples on implementing this solution can be found at jQuery DataTables: Using WHERE, JOIN and GROUP BY with ssp.class.php.

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
