array to generate form - php

Question

I am trying to use an array to output a form with the following function:
public function createArrayForm($table, $do, $formDesc = '', $id, $array, $markFields = false) {
if (!isset($table) && !isset($do)) {
self::show_error('One or more parameters are missing in ' . __FUNCTION__);
} elseif ($table == 'update' && !isset($id)) {
self::show_error('For this form to be built, and ID must be set. Missing parameter `ID` in ' . __FUNCTION__);
}
if (is_array($array) && $do == 'insert') {
$out .= '<form action="' . $_SERVER['PHP_SELF'] . '?id=' . $id . '&table=' . $table . '" method="post" class="form-horizontal" ' . $formAppend . '>';
$out .= '<div class="form-desc">' . $formDesc . '</div>';
$out .= $markFields ? '<h3>Input Fields</h3>' : '';
foreach ($array as $type => $fieldname) {
if ($type == 'input') {
$out .= generateInputField($fieldname);
}
}
$out .= $markFields ? '<h3>Content Fields</h3>' : '';
foreach ($array as $type => $fieldname) {
if ($type == 'textarea') {
$out .= generateTextarea($fieldname, $cke);
}
}
$out .= $markFields ? '<h3>Images Fields</h3>' : '';
foreach ($array as $type => $fieldname) {
if ($type == 'image') {
$out .= generateImgField($fieldname);
}
}
$out .= form_hidden('user_data', '1');
$out .= form_hidden('id', self::generateID());
$out .= form_close();
return $out;
}
And call:
$arr = array("textarea"=>"project_name", "input"=>"created", "input"=>"last_modified", "input"=>"published");
echo $automate->createArrayForm('projects', 'insert', 'Some form desc', '123', $arr, true);
But it only outputs:
When it should look something like this:
Only one of each, for example input, is returned. Rather than all instances of it. So "input"=>"created", "input"=>"last_modified", "input"=>"published" should make three inputs, but it only returns one.

Answer 1

You're re-using array keys. So
$arr = array("textarea"=>"project_name", "input"=>"created", "input"=>"last_modified", "input"=>"published");
will end up looking like this:
$arr = array("textarea"=>"project_name", "input"=>"published");
Instead, modify your code to something like this:
$arr = array("textarea"=>array("project_name"), "input"=>array("created", "last_modified", "published"));
Then take those individual arrays, and iterate through them.
foreach ($array['input'] as $fieldname) { // etc and so on

Answer 2

In PHP, you cannot have arrays that share keys.
You'll be best creating a simple array, and creating sub-entries, so that you maintain order, but can have more than one input/textarea.
Like so:
$arr = array(
array('type' => 'textarea', 'name' => 'project_name'),
array('type' => 'input', 'name' => 'created'),
array('type' => 'input', 'name' => 'published'),
array('type' => 'input', 'name' => 'last_modified')
)
This would also allow you to add more parameters than type/name.

Answer 3

The problem is that you use the same key for everything in the array.
A possibility would be to exchange values and keys
$arr = array("textarea"=>"project_name", "input"=>"created", "input"=>"last_modified", "input"=>"published");
[...]
foreach ($array as $fieldname => $type) {
if ($type == 'textarea') {
$out .= generateTextarea($fieldname, $cke);
}
}
