I have searched widely for this problem but to no avail. Here's the code that's giving me the issue.
if ($request->hasFile("images")) {
foreach ($request->file("images") as $i => $image) {
$path = $image->storePubliclyAs($product->id, "image_$i.{$image->extension()}");
}
}
The line with $image->storePubliclyAs() is raising the error:
InvalidArgumentException: Found 1 error while validating the input provided for the GetObject operation:
[Key] expected string length to be >= 1, but found string length of 0 in file /var/www/html/vendor/aws/aws-sdk-php/src/Api/Validator.php on line 65
I should note that I've already indicated in the .env file that the filesystem disk should be pointed to S3. The bucket's objects are also entirely public. This is quite confusing as $image->storeAs() works perfectly fine.
Found a workaround. Instead of using the storePubliclyAs() method, just use storeAs() and Storage::setVisibility() respectively:
if ($request->hasFile("images")) {
foreach ($request->file("images") as $i => $image) {
$path = $image->storeAs($product->id, "image_$i.{$image->extension()}");
Storage::setVisibility($path, "public");
}
}
Kind of weird but it's been the only way I could get it to work.
Can you try this code below. I just changed how you are using $i in giving the image a name.
if ($request->hasFile("images")) {
foreach ($request->file("images") as $i => $image) {
$path = $image->storePubliclyAs($product->id, "image_".$i.{$image->extension()}");
}
}

It drives me crazy ... I try to parse a csv file and there is a very strange behavior.
Here is the csv
action;id;nom;sites;heures;jours
i;;"un nom a la con";1200|128;;1|1|1|1|1|1|1
Now the php code
$required_fields = array('id','nom','sites','heures','jours');
if (($handle = fopen($filename, "r")) !== FALSE)
{
$cols = 0;
while (($row = fgetcsv($handle, 1000, ";")) !== FALSE)
{
$row = array_map('trim',$row);
// Identify headers
if(!isset($headers))
{
$cols = count($row);
for($i=0;$i<$cols;$i++) $headers[strtolower($row[$i])] = $i;
foreach($required_fields as $val) if(!isset($headers[$val])) break 2;
$headers = array_flip($headers);
print_r($headers);
}
elseif(count($row) >= 4)
{
$temp = array();
for($i=0;$i<$cols;$i++)
{
if(isset($headers[$i]))
{
$temp[$headers[$i]] = $row[$i];
}
}
print_r($temp);
print_r($temp['action']);
var_dump(array_key_exists('action',$temp));
die();
}
}
}
And the output
Array
(
[0] => action
[1] => id
[2] => nom
[3] => sites
[4] => heures
[5] => jours
)
Array
(
[action] => i
[id] =>
[nom] => un nom a la con
[sites] => 1200|128
[heures] =>
[jours] => 1|1|1|1|1|1|1
)
<b>Notice</b>: Undefined index: action in <b>index.php</b> on line <b>110</b>
bool(false)
The key "action" exists in $temp but $temp['action'] returns Undefined and array_key_exists returns false. I've tried with a different key name, but still the same. And absolutely no problem with the others keys.
What's wrong with this ?
PS: line 110 is the print_r($temp['action']);
EDIT 1
If i add another empty field in the csv at the begining of each line, action display correctly
;action;id;nom;sites;heures;jours
;i;;"un nom a la con";1200|128;;1|1|1|1|1|1|1
Probably there is some special character at the beginning of the first line and trim isn't removing it.
Try to remove every non-word character this way:
// Identify headers
if(!isset($headers))
{
for($i=0;$i<$cols;$i++)
{
$headers[preg_replace("/[^\w\d]/","",strtolower($row[$i]))] = $i;
....
If your CSV file is in UTF-8 encoding,
make sure that it's UTF-8 and not UTF-8-BOM.
(you can check that in Notepad++, Encoding menu)
I had the same problem with CSV files generated in MS Excel using UTF-8 encoding. Adding the following code to where you read the CSV solves the issue:
$handle = fopen($file, 'r');
// ...
$bom = pack('CCC', 0xef, 0xbb, 0xbf);
if (0 !== strcmp(fread($handle, 3), $bom)) {
fseek($handle, 0);
}
// ...
What it does, is checking for the presence of UTF-8 byte order mark. If there is one, we move the pointer past BOM. This is not a generic solution since there are other types BOMs, but you can adjust it as needed.
Sorry I am posting on an old thread, but thought my answer could add to ones already provided here...
I'm working with a Vagrant guest VM (Ubuntu 16.04) from a Windows 10 host. When I first came across this bug (in my case, seeding a database table using Laravel and a csv file), #ojovirtual's answer immediately made sense, since there can be formatting issues between Windows and Linux.
#ojovirtual's answer didn't quite work for me, so I ended up doing touch new_csv_file.csv through Bash, and pasting contents from the 'problematic' CSV file (which was originally created on my Windows 10 host) into this newly-created one. This definitely fixed my issues - it would have been good to learn and debug some more, but I just wanted to get my particular task completed.
I struggled with this issue for a few hours only to realize that the issue was being caused by a null key in the array. Please ensure that none of the keys has a null value.
I struggled with this issue until I realised that my chunk of code has been run twice.
First run when index was present and my array was printed out properly, and the second run when index was not present and the notice error is triggered. That left me wondering "why my obviously existing and properly printed out array is triggering an 'Undefined index' notice". :)
Maybe this will help somebody.
I've already asked a couple of questions regarding this and each step gets me closer however it still doesnt work as intended.
I want to upload an image and write it to the textfile, then when i upload another image that will be written to the end and so on so forth. So ultimately you'll have a long file with lots of images.
As far as i can tell my code should work but it doesn't. Here is a link to the site website for testing. Testing it maybe useful and below is the code.
It also always creates an empty element at the end of the array as you'll see from testing the site.
The PHP:
$sFileName = "imgDB.txt";
for ($i=0 ; $i < count($_FILES) ; $i++) {
move_uploaded_file(
$_FILES['file-'.$i]['tmp_name'],
"img/". $_FILES['file-'.$i]['name']
);
}
$sImgs = file_get_contents($sFileName); //gets a string from the file.
if (json_decode($sImgs, true) != false) {
$ajImgs = json_decode($sImgs, true);
} else {
$ajImgs = array();
}
$aOutPut = array_merge ($ajImgs, $_FILES);
$aSendToFile = json_encode(
$aOutPut,
JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE
);
file_put_contents($sFileName, $aSendToFile);
Some remarks
if the move_uploaded_file call is not protected further, this allows to upload any files, including script files - this opens a security vulnerability in your application - check for MIME-type and file-extension to avoid this
json_decode returns null if the input value is empty or cannot be decoded - not false like in your code
appending to an array is not done with array_merge, this just overrides the properties of $_FILES of the previous execution - use $aOutPut[] = $_FILES; instead
I have an array, which contains amongst other things a file path to a video file. There are various file formats .avi, .mp4 etc etc.
Now I only want to display the rows where the file path's file extension is .mp4.
Currently I'm using a function to extract the file extension, but I'm having trouble doing this on the fly while displaying the rows.
An example of the file path: c:\TempVideoDir\Office-P-cam01-20140826-083016.avi
The function im using to get the file ext:
function get_fileext($filename) {
$cut_fileext = (explode('.', $filename));
$just_fileext = $cut_fileext[1];
echo $just_fileext;
}
Which works fine.
Now I'm querying the database to get the filepath along with other details about the file, and I only want to display the rows where the file path contains a .mp4 file.
I've tried everything I could thing of/find on Google etc but this is what I currently have:
$stmt->execute();
$result = $stmt->fetchAll();
foreach($result as $row) {
if (in_array((get_fileext($row["Filename"])== "mp4"), $result)) {
echo " blah blah
I dont have the option of adding the file extension into the database table as this is backed up automatically by a piece of equipment.
So, whadoyareckon? is it possible to do it on the fly like this?
Any help is much appreciated!
Thanks
I dont think you can use in_array() like that. Its searching the entire index of the array, so when it looks ate $result[] its never going to find $row['filename'] with only an ext.
try this:
//looping through $result array
foreach($result as $row) {
//check if $row['filename'] has a string with a mp4 extension.
if (get_fileext($row["Filename"])== "mp4") {
echo "Row has a filename with the mp4 extension';
also as someone else pointed out fix your get_fileext() method to return something.
function get_fileext($filename) {
$cut_fileext = (explode('.', $filename));
$just_fileext = $cut_fileext[1];
return $just_fileext;
}
Your function isn't returning a value. It's emitting the value to the output:
function get_fileext($filename) {
$cut_fileext = (explode('.', $filename));
$just_fileext = $cut_fileext[1];
echo $just_fileext;
}
So there's no way for anything invoking that function to see that result. Instead, return the value:
function get_fileext($filename) {
$cut_fileext = (explode('.', $filename));
$just_fileext = $cut_fileext[1];
return $just_fileext;
}
That way the invocation of the function itself evaluates to the returned value, allowing you to use the function in your logic.
You could consider adjusting your database query to only return rows with ".mp4" files.
Change your query to have something like:
filepath = "%.mp4"
In MySQL the % operator is a wildcard, so this will match any strings ending in ".mp4"

I've been trying to make a simple website that lets you specify a directory, and embeds a player for each mp3 in whatever directory the user specifies. The problem is that no matter how I enter the directory name, glob() does not return any files. I've tried this with local folders, server directories, and the same folder as the php file.
'directoryPath' is the name of the text box where the user enters, you guessed it, the directory path. The 'echo $files' statement displays nothing onscreen. The 'echo "test"' statement DOES run, but the 'echo "hello"' statement in the loop does not execute.
Any help is appreciated!
if (!empty($_POST['directoryPath']))
{
$path = ($_POST['directoryPath']);
$files = glob("$path/{*.mp3}", GLOB_BRACE);
echo $files[0];
echo "test";
foreach($files as $i)
{
echo "hello";
echo $files[$i];
?>
<embed src=<?php $files[$i]; ?> width=256 height=32 autostart=false repeat=false loop=false></embed><?php echo $files[$i] ?></p>
<?php;
}
unset($i);
}
Validate the input first:
$path = realpath($_POST['directoryPath']);
if (!is_dir($path)) {
throw new Exception('Invalid path.');
}
...
Additionally check the return value glob returns false on error. Check for that condition (and ensure you are not using one of those systems that even return false when there are no files found).
I hope this is helpful. And yes, check your error log and enable error logging. This is how you can see what is going wrong.
Also see the following related function for a usage-example and syntax of GLOB_BRACE:
Running glob() from an included script returns empty array
One one tool I find very useful in helping debug variables in PHP is var_dump(). It's a function that provides you with information about a variable's type, it's contents, and any useful metadata it can attain from that variable. This would be a very useful tool for you here, because you'll quickly realize what you have in the variable $i is not at all what you expect.
$files = glob("$path/{*.mp3}", GLOB_BRACE);
foreach ($files as $i) {
var_dump($i);
}
/* Here's a hint, $i is not an index to the $files array.
So $files[$i] makes no sense. $i is actually the value not the key.*/
foreach ($files as $key => $value) { // very different from
// $key is the key to the current element of $files we're iterating over
// $value is the value of the current element we're iterating over
}
So in your code $i is the value not the key. See http://php.net/foreach for more information on how the construct works.
Also, what should be noted here is that you are using a relative path, whereas glob will return an absolute path. By relative this means your searching relative to the CWD (Current Working Directory) of your PHP script. To see wha that is you can use the following code.
var_dump(real_path('.'));
// similarly ...
var_dump(getcwd());
