Can I run the $_POST array through a loop to get the same result as the following code?
$_POST['manufacturer'] = strip_tags($_POST['manufacturer']);<br>
$_POST['part_no'] = strip_tags($_POST['part_no']);<br>
$_POST['product_name'] = strip_tags($_POST['product_name']);<br>
$_POST['link'] = strip_tags($_POST['link']);<br>
Or is there a way to apply strip_tags() to every field in the $_POST array?
$_POST itself unaltered, because it avoids any confusion later.
<?php ?> ). You can also nest them like this $form = array_map("trim", array_map("strip_tags", $_POST));As previously stated, array_map() is the function you're looking for
However, be aware that if one of your array values is itself an array, strip_tags will nullify that value. The key will remain in the parent array, but the value of that key will be null. Here's a function I use in place of array_map to avoid this. A possible use is if you have html input field arrays in your $_POST. For example, several inputs with a name like name="hello[]"
function strip_tags_array($array){
$result=array();
if(is_array($array)){
foreach($array as $key=>$value){
if(is_array($value)){
$result[$key]=strip_tags_array($value);
}
else if(is_string($value)){
$result[$key]=strip_tags($value);
}
else{
$result[$key]=$value;
}
}
}
return $result;
}
$_POST = strip_tags_array($_POST);
Could not get any of the examples to work on my server. Are you folks testing solutions? This works for me:
// no code
$allowcode=""; // put allowed code tags here
foreach ($_POST as $key => $value) { $$key=strip_tags($value, $allowcode); }
foreach ($_GET as $key => $value) { $$key=strip_tags($value, $allowcode); }
If you do not want to use any PHP inbuilt function, you can do like below:
foreach($_POST AS $key=>$val)
{
$_POST[$key] = strip_tags($val);
}
