how to display an error message in an array - php

Question

i have this code:
$allowed_extension = array('jpg', 'jpeg', 'png', 'bmp', 'tiff', 'gif');
$errors = array();
$output = array();
if(!empty($_FILES['image']['tmp_name'])){
foreach($_FILES['image']['name'] as $key => $array_value){
if(!in_array(pathinfo($_FILES['image']['name'][$key], PATHINFO_EXTENSION), $allowed_extension)){
die("Die!");
}
}
foreach($_FILES['image']['name'] as $key => $array_value){
$file_name = $_FILES['image']['name'][$key];
$file_size = $_FILES['image']['size'][$key];
$file_tmp = $_FILES['image']['tmp_name'][$key];
$file_extension = pathinfo($file_name, PATHINFO_EXTENSION);
$file_extension = strtolower($file_extension);
if (!in_array($file_extension, $allowed_extension)){
$errors[$file_name][] = "format $file_extension in image $file_name is not accepted";
continue;
}
if ($file_size > 2097152){
$errors[$file_name][] = "maxsize of 2MB on $file_name has reached";
}
if (count($errors) == 0){
$dir = "a/b/c";
if (is_dir($dir)){
mkdir("a/b/c/tmp_images", 0755);
}else{
mkdir("a/b/c", 0755);
mkdir("a/b/c/tmp_images", 0755);
}
$path = "a/b/c/tmp_images";
$prifix = basename($file_name, "." . $file_extension);
//var_dump ($prifix);
$uploadfile = $path . "/" . $file_name;
$x = 0;
while (file_exists($uploadfile)){
$x ++;
$uploadfile = "{$path}/{$prifix}-{$x}.{$file_extension}";
}
if (move_uploaded_file($file_tmp, $uploadfile)){
$file_name = basename($uploadfile);
$output [$file_name] = "OK";
}else{
$output[$file_name] = "Failure while Uploading!";
$errors[$file_name][] = "Failure: Can't move uploaded pictures!";
}//else...
}//if(count($errors))...
}//foreach($_FILES['image']['name']...
}//if(!empty($_FILES['image']['tmp_name'])...
and my problem is, that i dont know how to display the error messages that should be shown, when the array
$errors
is given. up to now, it just will be displayed:
array
instead of:
maxsize of 2MB on abc.jpg has reached
in the html i have this code:
<?php if(isset($errors)):?>
<div class="form-error-message" id="signup-error-message" style="display": none;">
<div class="arrow-wrapper">
<div class="border-wrapper">
<?php foreach($errors as $error):?>
<p class="layer-content">
<?php echo $error;?>
</p>
<?php endforeach;?>
</div>
</div>
</div>
if there is someone who could be that friendly and help me out i really would appreciate. thanks a lot.

Answer 1

Maybe save each error like this:
$errors = array();
$errors[] = $file_name . ": this is the error message.";
And display like this:
if(count($errors) > 0){
foreach($errors as $e){
echo $e . "<br />";
}
}

Answer 2

You've wrote $errors as 2-dimensional array:
$errors[$file_name][] = 'your message';
So to correctly display it use two foreach's instead of one:
<?php foreach($errors as $errorsOnFile):?>
<?php foreach($errorsOnFile as $error):?>
<p class="layer-content">
<?php echo $error;?>
</p>
<?php endforeach;?>
<?php endforeach;?>

Answer 3

How about?
echo implode(', ', $errors[$filename]);

Answer 4

You have to print_r an array, not echo it:
print_r($errors);
Alternatively, you can show each of the errors individually, like so:
foreach( $errors as $innerErrors )
{
foreach( $innerErrors as $anError )
{
echo $anError ."\n";
}
}

Answer 5

You can't just echo an array. You can, however, loops through the elements of the array.
foreach($errors[file_name] as $error_message) {
echo $error_message."<br>";
}
This code echos the errors one at a time.
