Generating the edit form

You did not think that we would leave the edit form without a code generator, did you? Of course we need to generate a php-file so that we can modify the code of the edit.php as well. The same strategy applies as for the list.php. So here we go. Create the file views/generic/edit_code.php

<?php
    $fields = $obj->fetchFields();
    $colCount = count($fields);
$code =
'<?php
    if (filter_input(INPUT_POST, 'save', FILTER_SANITIZE_URL) != '') {
';
        foreach ($fields as $f) {
            $name = $f->varName;
            if ($t->columnName == 'id') {
                // do nothing;
            } else {
$code .=
'        $obj->' . $name . ' = filter_input(INPUT_POST, '' . $f->columnName . '');
';
            }
        }
$code .=
'        $obj->update();
        ?>
        <div class="information">

        </div>
        <?php
    }

    <h1>File generated</h1>
    <pre><code>
        <?php echo str_replace('<', '<', $code); ?>
    </code></pre>
</div>

Now you can type index.php?modue=[your_module]&view=edit&generate=code and the edit file will be generated along with the code that will be printed on the screen. Enjoy!
