<? /* bastien koert Aug 2004 www.bastienkoert.net This code writes out all the needed DB fields for insert / update statements as well as generating the $global code, the post/get code and the initialization code with defaults from the db tables http://codewalkers.com/seecode/494.html Hi All, The most tedious part of coding any db interaction is the defining/initialization of the variables that interact with the db. All those POST/GET elements, the global elements and the development of the sql statements. This code takes the work out of that. Simply fill in the form to point it to a database and table and run it...the output shown is to : 1. initialize all db variables 2. generate the POST/GET values from the forms. 3. generate the global variables 4. generate the insert statement 5. generate the update statement It will look for primary keys, adapt to place quotes only around the text elements, and fill in the default db values where needed. There is always room for improvement, but this really reduces the workload when working on pages that map to one table. You can copy the code generated from the screen, or for a little more formatted code, view source, copy and remove the tags enjoy, bastien 10 September 2005 -------------------------------------------------- A few tweaks added by a much lazier guy than Bastien... - a place to set db variables for that db you're always using - generation of a SELECT query - PHP code snippets for extracting ONE Value and MANY values - checkbox to enable htmlspecialchars protection - generation of a table-formatted form in two versions: - all of it tucked into a single php variable - html with embedded php variables - checkbox to color every other row in the table - checkbox to add a "t" to form variable names AND retrieved vari names (useful when form used to set session variables... which CANNOT be directly by a form so you have to give them another name first) - handy table format Unfortunately, the option to view the source for better formatted code not an option: to show the HTML I had to convert it to its special characters... source code is therefore a MESS!!
