Symbi0nt's Model Validation (examples) | |
| Type: Sample Code (HOWTO) |
Category: Other |
| License: GNU General Public License |
Language: PHP |
| Description: This are the examples for my app_model.php These are three examples of Models, thus you should see how to use the validation. Below two expamples from the view. NOTW: if you start to add your own validation methods like seen in example 2, use $args = func_num_args(); print_r($args) to see what the function gives you. | |
