Okay .. I want any number of forms to be displayed on this page. My view is a loop that goes through the form array data, which is set in the controller. I'll rip out logic regarding success/fail on validation etc as that doesn't seem appropriate here.
First, the view code. There's a little bit of HTML preamble here, and then straight into the loop. I suspect there's a better way of assigning the 'name' and 'value' bits within hidden() or submit() calls.
Code:
foreach ($search_form_data as $form) {
echo form_open ($form["target"]);
echo $form["preamble"] . " ";
foreach ($form["input"] as $input_preamble=>$input_data) {
echo $input_preamble . " : ";
echo form_input ($input_data);
echo " ";
}
echo form_hidden ($form["hidden"]["name"], $form["hidden"]["value"]);
echo form_submit($form["submit"]["name"], $form["submit"]["button"]);
echo form_close ();
echo "<hr>";
}
The code in the controller to generate the array. I have this being loaded via a call to a private function but you could do it within your search method if you preferred. I also needed a way of having multiple text boxes within each form. Note that I haven't got any facility for other types of form elements (radios, etc) .. but will implement that stuff when I need it. I expect it will fit into this structure reasonably well.
Oh, and people that know what they're doing -- be gentle when you read this.
Code:
$search_form_data = array (
array (
"preamble" => "Search on scientific name", // This determines the form preamble
"target" => "organism/search", // Goes into form_open()
"input" => array ( // Multiple form_input() in a single form
"Genus" => array ( // Preamble for text box
'name' => 'search_genus', // form_input takes 'name' and 'value'
'value' => $posted_values['value_search_genus'],
),
"Species" => array (
'name' => 'search_species',
'value' => $posted_values['value_search_species'],
),
),
"hidden" => array ( // All forms are identified by hidden()
"name" => "search_type",
"value" => "sci",
),
"submit" => array ( // Submit button and name
"button" => "Go looking!",
"name" => "submit_sci",
),
),
// Obviously this stuff is repeated for extra forms
);
Hmmm .. the forum has munged my tabs. Oh well.
