PHP - Need Help Figuring Out An Exception To A Soapcall

Hey Guys. I am across this in a book and I am having a hard time understanding how I can try/catch this expception   The code below will throw an exception if I add an unit object into Archer or LaserCannon object.   Here is a quick example

class UnitException extends  Exception{}

abstract class Unit{



    function AddUnit(Unit $unit){
        throw new UnitException(get_class($this)."is a leaf");
    }
    function removeUnit(Unit $unit){
        throw new UnitException(get_class($this)."is a leaf");

    }

    

    abstract function bombardStrength();


}

class Archer extends  Unit {
    function bombardStrength(){
        return 4;
    }
}




class LaserCannonUnit extends  Unit {
    function bombardStrength(){
        return 44;
    }
}

$laser_cannon = new LaserCannonUnit();
$laser_cannon->AddUnit(New Archer()); // This is not allowed

When I run the client code I get the following error message   Fatal error: Uncaught exception 'UnitException' with message 'LaserCannonUnitis a leaf'   Can any please help me understand this?? Thanks!

Hey, I'm wondering what the issue is, I'm new to using PDO and objects so I'm sure this is a common error but setting me on the right track would be greatly appreciated.

Code: [Select]
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND password = d41d8cd98f00b204e9800998ecf8427e' at line 1' in /Users/JPFoster/Sites/Jaipai.Blog/engine.php:47 Stack trace: #0 /Users/JPFoster/Sites/Jaipai.Blog/engine.php(47): PDO->query('SELECT * FROM u...') #1 /Users/JPFoster/Sites/Jaipai.Blog/index.php(7): SiteEngine->login('', '') #2 {main} thrown in /Users/JPFoster/Sites/Jaipai.Blog/engine.php on line 47 Code: [Select]
public function login($user, $pw){
$user = addslashes($this->user);
$pw = md5($pw);

$query = "SELECT * FROM users WHERE username = ".$user." AND password = ".$pw;

//set up query
$results = $this->pdo->query($query);
$num_rows = $results->num_rows;

if ($num_rows == 1){
$row = $results->fetch_assoc();
echo "Worked!";
//$this->set_session($row['id'], $row['username'], $row['email']);
} else {

echo "Your Username and Password did not match";

}

//if user + passs match { redirect (member page) and set up sessions

// Else ... Retry...
}


}
I don't see an issue with my query, and the object is instantiated by having the submit button isset() and i use login($_post[user], $_post[pw])

How to get cURL timedout Exception or cURL timedout Message ?

Hi ! I was seeing the Exception class defined in basic.php and I found that all the methods are final and without body:
Code: [Select]
final public function getMessage () {}But if I call MyCustomException->getMessage() I get the message.
How does it works??

Hi guys, I'm reviewing a piece of small web application and the current application does not have any error / exception handling capability. If there is any error, it would simply show an error message followed by die;.

I'm planning to implement a simple exception handling class to handle the errors. What I'm thinking is a simple redirect when an error is being caught together with an error code that correspond to an error message in a simple flat text file. The error page will then show an error message that corresponds to the code.

Here's what I have so far. Would appreciate if the PHP experts here would give simple pointers to enhance it.

<?php
class MyException extends Exception {}

try {
throw new MyException("error.php");
}

catch (MyException $e) {
$file = $e->getMessage();
header("Location: $file?e=1");
}

?>

This is what I have on my error.php page

<?php
$errorcode = $_GET['e'];

function getErrorMessage($errorcode) {
$errors = file("english.txt");
foreach ($errors as $error) {
list ($key,$value) = explode(",",$error,2);
$errorArray[$key] = $value;
}
return $errorArray[$errorcode];
}
echo "Test <br />";
echo getMessageMap($errorcode);
?>

As you can see here, exception class would redirect user to error.php if an error is caught together with a GET variable on the URL. On error.php page, it would GET the error code and then run it through a function to get the error message of the corresponding error code and then echos it out.

Was wondering if this is a good practice? My ultimate goal here is to avoid displaying the error message itself on private includes file.

Thank you in advance for your suggestions.

In drive.php   public function insert($postBody, $optParams = array())

I know this is stupid newbie stuff, but I can't think about this the right way.  And this question might very well make NO sense. If so, I apologize in advance.  I'm trying to consolidate code.  I basically have lots of quizzes, all with their own answers, which I compare using AJAX.  I had individual pages for each quizzes answers to do that comparison and everything was working fine.  It would do the following...
Code: [Select]
<?php
$userinput = strval($_GET['userinput']);
$userinput= trim($userinput);
$userinput = strtolower($userinput);

switch ($userinput) {
     case 'heat':
 case 'miami heat':
          echo 'Miami Heat';
          exit;
     case 'magic':
 case 'orlando magic':
          echo 'Orlando Magic';
          exit;
     case 'jazz':
 case 'utah jazz':
          echo 'Utah Jazz';
          exit;

        
     default:
          echo 'incorrectguess';
}
?>
But now I am storing the answers in a MySQL database (for example, one answer set is in the database as "Miami Heat/heat/miami"...each allowed answer is separated by a "/", with the first answer being the "main" correct answer).  So now, I want to just have ONE "comparison" page and populate the "cases" into that page dynamically, from the database.  This is what I came up with so far, but it's not working...

Code: [Select]
<?php

$userinput = strval($_GET['userinput']);
$userinput= trim($userinput);
$userinput = strtolower($userinput);


if ($_GET['quizid'] == "") {
redirect_to('index.php');
} else {
$quizid=$_GET['quizid'];
}

$sql = "SELECT * FROM answers
WHERE quizid = $quizid";
$result = mysql_query($sql, $connection);
if (!$result) { 
die("Database query failed: " . mysql_error());
} else {

switch ($userinput) {

while ($results = mysql_fetch_array($result)) {
$answers = explode("/", $results['answer']);
$n = count($answers);
for ($i=1; $i < $n; $i++) {
case '$answers[$i]':
}
echo '$answers[0]';
exit;

 
 default:
echo 'incorrectguess';
  
}

}
?>

What I'm having trouble grasping is where I need to use "echo" or NOT use "echo".  For example, where I have "switch ($userinput) {" in the NEW code, does that need to actually be "echo 'switch ($userinput) {';"?

I'm trying different combos and failing, so just curious if someone can help me understand what, if anything, needs to be echoed when doing it the 2nd way (dynamic info) rather than the 1st way (static info)

I'm sure it's not much, but I'm not understanding something with custom error handlers:

I've created a custom error handler, which I initially set when my page loads :

set_error_handler(array ( new ErrorHandler(), 'handleError' ));

 

It seems to catch all internal PHP errors, such as if I: var_dump($non_existing_var); right after the set_error_handler....

Now, I have an object that throws an exception after:

set_error_handler(array ( new ErrorHandler(), 'handleError' )); 
$locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception 
...

I thought that with an error handler set, I could 'skip' the try/catch for it, but doing so, PHP spits out in its internal log:

PHP Fatal error: Uncaught CorbeauPerdu\i18n\LocaleException: ....

 

My error handler doesn't catch it at all before, thus my page breaks!!

If I want it to go through the error handler, I have to init my Locale with a try/catch and use trigger_error() like so:

set_error_handler(array ( new ErrorHandler(), 'handleError' ));

try { 
  $locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception 
}
catch(Exception $e) { 
  trigger_error($e->getMessage(), E_USER_ERROR); 
} 
...

Is this normal ? I thought one of the goals of the error_handler was to catch anything that wasn't dealt with?

Thanks for your answers!

Hi

I am implementing a read-only access to some specific attributes of a class via the magic __get method. I intend to raise an exception when trying to write to it using __set, but I'm not sure which exception is suitable to use.

Is there any predefined exception to indicate such an error or should I just go ahead and define my own?

Hello all,   Appreciate if you folks could pls. help me understand (and more importantly resolve) this very weird error:     Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC, purchase_later_flag ASC, shopper1_buy_flag AS' at line 3' in /var/www/index.php:67 Stack trace: #0 /var/www/index.php(67): PDO->query('SELECT shoplist...') #1 {main} thrown in /var/www/index.php on line 67   Everything seems to work fine when/if I use the following SQL query (which can also be seen commented out in my code towards the end of this post) :  

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
           FROM shoplist, store_master, item_master
           WHERE     shoplist.store_id = store_master.store_id
                   AND shoplist.item_id = item_master.item_id";

  However, the moment I change my query to the following, which essentially just includes/adds the ORDER BY clause, I receive the error quoted above:

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name 
		FROM shoplist, store_master, item_master 
		ORDER BY purchased_flag ASC, 
				purchase_later_flag ASC, 
				shopper1_buy_flag ASC, 
				shopper2_buy_flag ASC, 
				store_name ASC) 
		WHERE 	shoplist.store_id = store_master.store_id 
				AND shoplist.item_id = item_master.item_id";

In googling for this error I came across posts that suggested using "ORDER BY FIND_IN_SET()" and "ORDER BY FIELD()"...both of which I tried with no success.   Here's the portion of my code which seems to have a problem, and line # 67 is the 3rd from bottom (third last) statement in the code below:  

                    <?php
                        /*
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
                                FROM shoplist, store_master, item_master
                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        */
                    
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
                                FROM shoplist, store_master, item_master
                                ORDER BY FIND_IN_SET(purchased_flag ASC,
                                                 purchase_later_flag ASC,
                                                 shopper1_buy_flag ASC,
                                                 shopper2_buy_flag ASC,
                                                 store_name ASC)
                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        $result = $pdo->query($sql);                        
                        
                        // foreach ($pdo->query($sql) as $row) {
                        foreach ($result as $row) {
                            echo '<tr>';
                                print '<td><span class="filler-checkbox"><input type="checkbox" name="IDnumber[]" value="' . $row["idnumber"] . '" /></span></td>';
