Checkbox $_POST remember

[mikenl]

Hi,

 

I generate a list of checkboxes like this:

 

// here I set an array, $rows is db query result

$language = array(1 => "Afrikaans","Albanian","Arabic","Armenian","Bangla","Bosnian","Bulgarian","Burmese","Catalan","Cebuano","Chinese","Croatian","Czech","Danish","Dutch","English","Esperanto","Estonian","Finnish","French","Gaelic","German","Greek","Hebrew","Hindi","Hungarian","Icelandic","Indonesian","Italian","Japanese","Korean","Kurdish","Latin","Latvian","Lithuanian","Luxembourgish","Macedonian","Malay","Norwegian","Persian","Polish","Portuguese","Romanian","Romansh","Russian","Serbian","Sign Language","Slovak","Slovenian","Sorbian","Spanish","Swedish","Swiss German","Tagalog","Thai","Turkish","Ukrainian","Welsh");

loadform2($language,$rows,'lang');

// here I create the checkbox list

function loadform2($values,$rows,$fieldname){

if($_POST){
	$output = $_POST;
	} else {
	$output = $rows;
}

$size = count($values);
?>
<div style="width:125px;height:100px;overflow:auto;margin-bottom:7px; padding:0">
  <?

foreach ($values as $key => $value){
	if(!empty($key)){
		echo "<input id=\"$fieldname".$key."\" name=\"$fieldname"."[]"."\" type=\"checkbox\" value=\"$key\"";
	if($_POST){

// how do I make this work? $output is $_POST data
				if ($output[0][$fieldname][$key] == $key-1) echo "checked";
				} else {
// this works, $output comes from db query
				if ($output[0][$fieldname.$key] == 1) echo "checked";
				}
		echo "/><label for=\"$fieldname".$key."\">$value</label><br />\n";
 		}
 	}		
 ?>
  <input name="<? echo $fieldname ?>_num" type="hidden" value="<? echo $size ?>" />

</div>
<?
}

 

I want to have all checkboxes that were checked when POSTed to 'stick' but don't know how to do this for $_POST data...

 

Anyone knows how to handle this?

[adam84]

hmmm will

if($_POST){

}

 

ever evaluate to true?

[mikenl]

yes

 

here's a print_f of $_POST:

[lang] => Array ( [0] => 1 [1] => 2 [2] => 58 ) 

boc 1, 2 and 58 are checked...

print_r of db query result:

 

[lang1] => 1 [lang2] => 1 [lang3] => 0 [lang4] => 0 [lang5] => 0 [lang6] => 0 [lang7] => 0 [lang8] => 0 [lang9] => 0 [lang10] => 0 [lang11] => 0 [lang12] => 0 [lang13] => 0 [lang14] => 0 [lang15] => 0 [lang16] => 0 [lang17] => 0 [lang18] => 0 [lang19] => 0 [lang20] => 0 [lang21] => 0 [lang22] => 0 [lang23] => 0 [lang24] => 0 [lang25] => 0 [lang26] => 0 [lang27] => 0 [lang28] => 0 [lang29] => 0 [lang30] => 0 [lang31] => 0 [lang32] => 0 [lang33] => 0 [lang34] => 0 [lang35] => 0 [lang36] => 0 [lang37] => 0 [lang38] => 0 [lang39] => 0 [lang40] => 0 [lang41] => 0 [lang42] => 0 [lang43] => 0 [lang44] => 0 [lang45] => 0 [lang46] => 0 [lang47] => 0 [lang48] => 0 [lang49] => 0 [lang50] => 0 [lang51] => 0 [lang52] => 0 [lang53] => 0 [lang54] => 0 [lang55] => 0 [lang56] => 0 [lang57] => 0 [lang58] => 1

print_r of $_POST (previous post has a o in it...):

 

[lang] => Array ( [0] => 1 [1] => 2 [2] => 58 )

Is there anyone on phpfreaks that can solve this?

Here's a slight rework that should work

 

<?php

$options = array(1 => "Afrikaans","Albanian","Arabic","Armenian","Bangla","Bosnian","Bulgarian","Burmese","Catalan","Cebuano","Chinese","Croatian","Czech","Danish","Dutch","English","Esperanto","Estonian","Finnish","French","Gaelic","German","Greek","Hebrew","Hindi","Hungarian","Icelandic","Indonesian","Italian","Japanese","Korean","Kurdish","Latin","Latvian","Lithuanian","Luxembourgish","Macedonian","Malay","Norwegian","Persian","Polish","Portuguese","Romanian","Romansh","Russian","Serbian","Sign Language","Slovak","Slovenian","Sorbian","Spanish","Swedish","Swiss German","Tagalog","Thai","Turkish","Ukrainian","Welsh");
$selections = ($_POST['languages'] ? $_POST['languages'] : array());

function checkList($options, $selections, $name) {
echo "<div style='width:500px;height:200px;overflow:auto;margin-bottom:7px; padding:0'>";
foreach ($options as $key => $value){
	echo "<input id='". $name . $key ."' name='". $name ."[]' type='checkbox' value='". $key ."' ". (in_array($key, $selections) ? "checked" : "") .">";
	echo "<label for='". $name . $key ."'>$value</label><br />\n";
}
echo "</div>";
}

?>

<form method='post'>
<?php checkList($options, $selections, 'languages'); ?>
<input type='submit'>
</form>
