When i'm trying to save my model like this if( !$myModel->save() ) I have to surround in try catch my condition if I want to get the errors messages... I can't check if the save() is false, because this will not returns the errors.
How can I do to get $myModels->getMessages() without using try catch ?
I want to do like this example and return json_encode if the save doesn't work.
The example from the docs, shows you how to get the messages after you save your $myModel
$robot = new Robots();
$robot->type = "mechanical";
$robot->name = "Astro Boy";
$robot->year = 1952;
if ($robot->save() == false) {
echo "Umh, We can't store robots right now: \n";
// get the messages of the saved Robot.
foreach ($robot->getMessages() as $message) {
echo $message, "\n";
}
} else {
echo "Great, a new robot was saved successfully!";
}

I am developing a PHP script that allows me to modify tags in an XML file and move them once done.
My script works correctly but I would like to add error handling: So that if the result of my SQL query does not return anything display an error message or better, send a mail, and not move the file with the error and move to the next.
I did some tests but the code never displays the error and it moves the file anyway.
Can someone help me to understand why? Thanks
<?php
}
}
$xml->formatOutput = true;
$xml->save($source_file);
rename($source_file,$destination_file);
}
}
closedir($dir);
?>
Give this one a try
$result = odbc_fetch_array($exec);
if ($result === false || $result['GEAN'] === null) {
echo "GEAN not found for $SKU_CODE";
// continue;
}
$barcode = (string) $result['GEAN'];
echo $barcode; echo "<br>"; //9353970875729
$node->getElementsByTagName("SKU")->item(0)->nodeValue = "";
$node->getElementsByTagName("SKU")->item(0)->appendChild($xml->createTextNode($result[GEAN]));
I am trying to create a profile editing setup. It seems as though the information is edited only when an image is being uploaded. I found out that allowing the error message to be a condition allows for some more manipulation so I attempted it now my condition statement is not working as it should.
if($_FILES['files']['error']==0) {
print_r($_FILES['files']['error']);
echo "if";
foreach($_FILES['files']['name'] as $file => $name) {
$filename = $name;
try{
if(move_uploaded_file($_FILES['files']['tmp_name'][$file],'uploads/'.$filename)) {
$updateInfo = $db->prepare("UPDATE users SET image = :image, aboutme = :aboutme WHERE id = :id");
$updateInfo->bindParam(":image", $filename);
$updateInfo->bindParam(":id", $_SESSION['user']['id']);
$updateInfo->bindParam(':aboutme', $aboutme);
$updateInfo->execute();
}
} catch(Exception $e) {
echo $e;
}
}
} elseif($_FILES['files']['error'] == 4) {
print_r($_FILES['files']['error']);
echo "Elseif";
try{
$updateInfo = $db->prepare("
UPDATE users
SET
aboutme = :aboutme
WHERE id = :id
");
$updateInfo->bindParam(':id', $_SESSION['user']['id']);
$updateInfo->bindParam(':aboutme', $aboutme);
$updateInfo->execute();
} catch(Exception $e) {
echo $e;
}
} else{
print_r($_FILES['files']['error']);
echo "else";
}
}
When I check what array is being sent, its the correct one but the wrong condition, ie: it would run the else statement no matter the file check.
My question:
Is there something wrong with my code, with the exception of any security or efficiency flaws?
$_FILES['files']['error'] returns error code along with the file array. There are different type of error codes, all codes are mentioned in following link with details:
Please check by
print_r($_FILES['files'])
and see what are you getting in response.
As you posted your array response, you can get error code by $_FILES['files']['error'][0] or use switch case as mentioned in following link.
See here for more details:
http://php.net/manual/en/features.file-upload.errors.php
Also regarding debugging, always debug code step by step from top to bottom. Check $_POST, $_FILES, $_SERVER etc details if you get some problem particular related to data process.
well i'm writing a php code to edit tags and data inside those tags but i'm having big trouble getting my head around the thing.
basically i have an xml file similar to this but bigger
<users>
<user1>
<password></password>
</user1>
</users>
and the php code i'm using to try and change the user1 tag is this
function mod_user() {
// Get global Variables
global $access_level;
// Pull the data from the form
$entered_new_username = $_POST['mod_user_new_username'];
$entered_pass = $_POST['mod_user_new_password'];
$entered_confirm_pass = $_POST['mod_user_confirm_new_password'];
$entered_new_roll = $_POST['mod_user_new_roll'];
$entered_new_access_level = $_POST['mod_user_new_access_level'];
// Grab the old username from the last page as well so we know who we are looking for
$current_username = $_POST['mod_user_old_username'];
// !!-------- First thing is first. we need to run checks to make sure that this operation can be completed ----------------!!
// Check to see if the user exist. we just use the normal phaser since we are only reading and it's much easier to make loop through
$xml = simplexml_load_file('../users/users.xml');
// read the xml file find the user to be modified
foreach ($xml->children() as $xml_user_get)
{
$xml_user = ($xml_user_get->getName());
if ($xml_user == $entered_new_username){
// Set array to send data back
//$a = array ("error"=>103, "entered_user"=>$new_user, "entered_roll"=>$new_roll, "entered_access"=>$new_access_level);
// Add to session to be sent back to other page
// $_SESSION['add_error'] = $a;
die("Username Already exist - Pass");
// header('location: ../admin.php?page=usermanage&task=adduser');
}
}
// Check the passwords and make sure they match
if ($entered_pass == $entered_confirm_pass) {
// Encrypt the new password and unset the old password variables so they don't stay in memory un-encrytped
$new_password = hash('sha512', $entered_pass);
unset ($entered_pass, $entered_confirm_pass, $_POST['mod_user_new_password'], $_POST['mod_user_confirm_pass']);
}
else {
die("passwords did not match - Pass");
}
if ($entered_new_access_level != "") {
if ($entered_new_access_level < $access_level){
die("Access level is not sufficiant to grant access - Pass");
}
}
// Now to load up the xml file and commit changes.
$doc = new DOMDocument;
$doc->formatOutput = true;
$doc->perserveWhiteSpace = false;
$doc->load('../users/users.xml');
$old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0);
// For initial debugging - to be deleted
if ($old_user == $current_username)
echo "old username found and matches";
// Check the variables to see if there is something to change in the data.
if ($entered_new_username != "") {
$xml_old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0)->replaceChild($entered_new_username, $old_user);
echo "Username is now: " . $current_username;
}
if ($new_pass != "") {
$current_password = $doc->getElementsByTagName($current_user)->item(0)->getElementsByTagName('password')->item(0)->nodeValue;
//$replace_password = $doc
}
}
when run with just the username entered for change i get this error
Catchable fatal error: Argument 1 passed to DOMNode::replaceChild() must be an instance of DOMNode, string given, called in E:\xampp\htdocs\CGS-Intranet\admin\html\useraction.php on line 252 and defined in E:\xampp\htdocs\CGS-Intranet\admin\html\useraction.php on line 201
could someone explain to me how to do this or show me how they'd do it.. it might make a little sense to me to see how it's done :s
thanks
$entered_new_username is a string so you'll need to wrap it with a DOM object, via something like$doc->createElement()
$xml_old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0)->replaceChild($doc->createElement($entered_new_username), $old_user);
This may not be quite right, but hopefully it points you in the correct direction.
alright got it writing and replacing the node that i want but i have ran into other issues i have to work out (IE: it's replacing the whole tree rather then just changing the node name)
anyway the code i used is
// For initial debugging - to be deleted
if ($old_user == $current_username)
echo "old username found and matches";
// Check the variables to see if there is something to change in the data.
if ($entered_new_username != "") {
try {
$new_node_name = $doc->createElement($entered_new_username);
$old_user->parentNode->replaceChild($new_node_name, $old_user);
}
catch (DOMException $e) {
echo $e;
}
echo "Username is now: " . $current_username;
}
if ($new_pass != "") {
$current_password = $doc->getElementsByTagName($current_user)->item(0)->getElementsByTagName('password')->item(0)->nodeValue;
//$replace_password = $doc
}
$doc->save('../users/users.xml');
I am using gigya php sdk, It works well I am able to post to user's wall or profile using socialise.setStatus method but I am have problems when I try to use the publishuseraction method. I get an error Invalid request signature.
$method = "socialize.publishUserAction";
$request = new GSRequest($apiKey,$secretKey,$method);
$userAction = new GSDictionary("{\"title\":\"This is my title\", \"userMessage\":\"This is a user message\", \"description\":\"This is a description\", \"linkBack\":\"http://google.com\", \"mediaItems\":[{\"src\":\"http://www.f2h.co.il/logo.jpg\", \"href\":\"http://www.f2h.co.il\",\"type\":\"image\"}]}");
$request->setParam("userAction", $userAction);
$request->setParam("uid", $userUID);
$response = $request->send();
if($response->getErrorCode()==0){
echo "Success";
} else {
echo ("Error: " . $response->getErrorMessage());
}
UPDATED AFTER USING $response->getLog()
apiMethod=socialize.publishUserAction
apiKey=correct_api_key
params={"userAction":{},uid":"MY_UID","format":"json","httpStatusCodes":"false"}
URL=http://socialize.gigya.com/socialize.publishUserAction postData=uid=urlencoded(MY_UID)&format=json&httpStatusCodes=false&apiKey=correct_api_key×tamp=1296229876&nonce=1.29622987636E%2B12&sig=HEdzy%2BzxetV8QvTDjdsdMWh0%2Fz8%3D
server= web504
I used both put method
$userAction = new GSDictionary();
$userAction->put("title", "This is my title");
$userAction->put("userMessage", "This is my user message");
$userAction->put("description", "This is my description");
$userAction->put("linkBack", "http://google.com");
$mediaItems = array();
$mediaItems[0] = new GSDictionary("{\"src\":\"http://www.f2h.co.il/logo.jpg\", \"href\":\"http://www.f2h.co.il\",\"type\":\"image\"}");
& JSON method
$userAction = new GSDictionary("{\"title\":\"This is my title\", \"userMessage\":\"This is a user message\", \"description\":\"This is a description\",
\"linkBack\":\"http://google.com\", \"mediaItems\":[ {\"src\":\"http://www.f2h.co.il/logo.jpg\", \"href\":\"http://www.f2h.co.il\",\"type\":\"image\"}]}");
I get the same error. And User action is empty using both methods. I appreciate any help.
Thanks.
Try calling getLog() for a bit more information about the error:
if($response->getErrorCode()==0){
echo "Success";
} else {
echo ("Error: " . $response->getErrorMessage());
print "<pre>";
print_r($response->getLog());
print "</pre>";
}
Also, are you able to run getUserInfo w/ the SDK? This is a simple test that also requires a signature. Use the example on the PHP SDK page (about 1/2 way down).
when I'm trying to getimagesize($img) and the image doesn't exist, I get an error. I don't want to first check whether the file exists, just handle the error.
I'm not sure how try catch works, but I want to do something like:
try: getimagesize($img) $works = true
catch: $works = flase
Like you said, if used on a non-existing file, getimagesize generates a warning :
This code :
if ($data = getimagesize('not-existing.png')) {
echo "OK";
} else {
echo "NOT OK";
}
will get you a
Warning: getimagesize(not-existing.png) [function.getimagesize]:
failed to open stream: No such file or directory
A solution would be to use the # operator, to mask that error :
if ($data = #getimagesize('not-existing.png')) {
echo "OK";
} else {
echo "NOT OK";
}
As the file doesn't exist, $data will still be false ; but no warning will be displayed.
Another solution would be to check if the file exists, before using getimagesize ; something like this would do :
if (file_exists('not-existing.png') &&
($data = getimagesize('not-existing.png'))
) {
echo "OK";
} else {
echo "NOT OK";
}
If the file doesn't exist, getimagesize is not called -- which means no warning
Still, this solution is not the one you should use for images that are on another server, and accessed via HTTP (if you are in this case), as it'll mean two requests to the remote server.
For local images, that would be quite OK, I suppose ; only problem I see is the notice generated when there is a read error not being masked.
Finally :
I would allow errors to be displayed on your developpement server,
And would not display those on your production server -- see display_errors, about that ;-)
Call me a dirty hacker zombie who will be going to hell, but I usually get around this problem by catching the warning output into an output buffer, and then checking the buffer. Try this:
ob_start();
$data = getimagesize('not-existing.png');
$resize_warning = ob_get_clean();
if(!empty($resize_warning)) {
print "NOT OK";
# We could even print out the warning here, just as PHP would do
print "$resize_warning";
} else {
print "OK"
}
Like I said, not the way to get a cozy place in programmer's heaven, but when it comes to dysfunctional error handling, a man has to do what a man has to do.
I'm sorry that raise such old topic. Recently encountered a similar problem and found this topic instead a solution. For religious reasons I think that '#' is bad decision. And then I found another solution, it looks something like this:
function exception_error_handler( $errno, $errstr, $errfile, $errline ) {
throw new Exception($errstr);
}
set_error_handler("exception_error_handler");
try {
$imageinfo = getimagesize($image_url);
} catch (Exception $e) {
$imageinfo = false;
}
This solution has worked for me.
try {
if (url_exists ($photoUrl) && is_array (getimagesize ($photoUrl)))
{
return $photoUrl;
}
} catch (\Exception $e) { return ''; }
Simple and working solution based on other answers:
$img_url = "not-existing.jpg";
if ( is_file($img_url) && is_array($img_size = getimagesize($img_url)) ) {
print_r($img_size);
echo "OK";
} else {
echo "NOT OK";
}
