PHP - Abstarct Static Inconsistent Error Handling

My script displays results until I hit an error.  I continually get fatal timeout errors that I am unable to handle or ignore.  Yes I googled and found the custom error handler AND the simpler try/catch.  Still cant figure it out...
It has been 1 hour of playing with this without success so I have to ask  .  Please help.  thanks : )

Code: [Select]
try
{
if(($result=shell_exec("$commandLine")) == false)
{
echo "------>error";
throw new Exception;
}
else
{
echo "---->good";
}
}
catch (Exception $e)
{
echo "@@@__>exception caught";
}

Hello everyone,

quick description of 'error handling' so that everyone understands the solution i am seeking. let php and the database handle the error is not an appropriate answer here.

find out what i mean: using xampp, go to a login screen of your website, then turn off the database before submitting the login data. the connection will be attempted then fail. the browser will display its own error page which is white bg with a message. this is ridiculous. i made a custom handler that allows me to ignore this failure and show my own website with an error message.

now how can i detect an error with a select or update statement? i am not a db designer, so i really don't know how to do it. what say i fetch filed['testmyerror'] and it doesn't exist or there is a problem. how do i write php code that is used to ignore this problem and display my own message. naturally i will log the error and/or log and send email to myself.

anyone able to help? just a tip in the right direction?

Thank you very much, i appreciate this forum and its members always.

Hopefully there is a simple solution to this.

I have a form that when submitted sends a message to an email address from the form.  A customer fills it out, so there is no single one email address.  However, half of the time, the retards that use this form dont know their own email address and dont bother to put the .net at the end of it.  or they misspell it.  The other half of the time they dont even bother to put the @ and the domain.  They still think this is AOL for some god unknown reason.  And I cant account for all the ways that they can not figure out how to fuck up their email address, so an email-validator doesnt work because they can even beat that and still manage to break it.  For example, one guy named Mike continues to put the first half of his email in as Miek or Mik or just spelled completely wrong, and the 550 error that comes up when he puts that garbage in, which is most of the time (I think the guy is blind or something) is because his email address doesnt exist on the mail server because he cant spell it right, when on the off chance he actually does get the @domain.com in the end.  I really hate my retard customers.

So my simple little form blows up on them.

But what I am trying to do is to have something like this

if(@mail(args))
  {
  //success, I'll call them back shortly
  }
else
  {
  //youre a retard, please put in your email address correctly
  }

However, the error handling isnt working.  mail() is supposed to return FALSE if it encounters an error, an error that I'd rather put in an error log and not display to the customer, however, the error suppressor doesnt work.

Any Suggestions?

Hi.

I'm trying to display all the missing fields (errors) when the user hits SUBMIT.

My logic:

IF there is NO EMAIL THAN add $errortrack array = $errormsg[EMAIL]

IF there is NO OLDPASSWORD THAN add $errortrack array = $errormsg[OLDPASS]

and so on.

At the end, Print ALL the Error messages on the form using <?php foreach ( $errortrack as $key => $value) { 
                echo "<dt>$key:</dt>"; } ?>

The only thing it prints out is "0:" ever though there should be other errors.

What am I missing?

Hey guys i was wondering if someone could help or guide me. I have been messing around with php for quite some months now to the stage where i can code pretty much what i need to. but recently i started using paypals IPN and during testing i realised some problems arise for example when testing and people buying things say the payment failed due to a line not executing in your script for what ever reason, the person has lost their money yet you have gained it and they are lost. Take this code below for example:


public function insertIntoDatabase($firstName,$lastName,$emailAddress,$merchant,$code,$database,$gameNumber)
{
$year = date("Y");
// Check what database we need to submit too::
$sql = "INSERT INTO playerGame (playerFirstName,
playerLastName,
playerEmailAddress,
playerAccountType,
playerCode,
playerGameDate,
playerGameNumber) VALUES (?,?,?,?,?,?,?)";

$stmt = $this->conn->prepare($sql);
$stmt->bind_param('ssssssi',$firstName,$lastName,$emailAddress,$merchant,$code,$year,$gameNumber);
$stmt->execute();
$stmt->close();

return true;
}


this is called on success the paypal IPN script. But what happens if this fails to execute? I suppose i could wrap it in a variable on the other side and test it

if($task)
{
    echo "code executed";
}

but what happens if this fails ? of am i just being paranoid ? hope someone can help dont want to be ripping people off =] Thanks!

Has anyone seen a decent database class for nicely wrapping up all the PDO functions? Ideally I'm after an example to handle database errors properly, insert/update/select queries, prepared statements and transactions. I've had a crack at writing my own and it's a bit messy with error handling everywhere. Maybe I need to put that in a separate class or something.

E.g. here's how I'd do a database update:
$db = new Database();    // In page controller
$params['type'] = $type;
$params['details'] = $details;
$query = 'insert into site_logs (type, details) values (:type, :details)';
$result = $db->preparedUpdate($query, $params);   // returns false if error or # of rows if successful

Just some examples would be great and I'll re-factor my one to make it better. Thanks!

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.

I thought I was a beginner PHPer but now I'm not even sure I'm that. I have this class here which starts with:
Code: [Select]
    private static $FormatType = "";
but then further down:
Code: [Select]
    public function SetFormatType($NewFormatTypeId)
    {
        $this->FormatType = $NewFormatTypeId;
    }
    public function GetFormatType()
    {
        return $this->FormatType;
    }
Do you suppose that the original developer just had a singleton or something, then latter on he found that he was making more instances and PHP tolerates this behavior? Or am I missing something?

Greetings, all -

Curious to know if someone wouldn't mind taking a look at this code and letting me know if there are any apparent errors that may cause this problem:

I attempted sending the message to one of my two 1and1 email accounts and after some delay, it sent it to 1and1 account B but not 1and1 account A.  My gmail account, however, gets them every time.  I'd like to just say it's some issue with 1and1 but since it successfully got through to the one 1and1 account I'm not comfortable stopping at that.  I should also mention that for some reason, as I'm trying it today, the successful 1and1 account will no longer receive the messages...  I've tried it with directly copying the php mail code from 1and1's FAQ, though, and it seemed to work for the 1and1 account that was previously succcessful (acct B) but not acct A.

Very stuck...

Thanks

$from = $_REQUEST['email'];
$subject = $_REQUEST['subject'];
$message = $_REQUEST['question'];
mail("username@domain.com", "Subject: $subject", $message, "From: $from");
echo "Mail sent";

I'm encountering some inconsistent behaviour with respect to variable substitution. I hope someone here can help me figure out why.

Let me explain what I'm trying to do. I am working on a prototype that is supposed to display a simple three-column MySQL table in ascending order by one or the other of the three columns. Exactly the same data (rows and columns) is shown each time; only the sequence of the rows differs. To accomplish this, I show the user a form with three radio buttons in a single group. The user chooses the radio button that represents the column which is to be used in the sort, then presses Submit. That invokes a script that contains PHP. The script reads the value passed from the form, which is the name of one of the three columns of the table, Series, Character, or Actor. and stores it in a variable name $SortKey. Then, the variable is used in ORDER BY clause of the SQL Query to cause sorting on that column. This all works perfectly for the first and third columns, Series and Actor. But when script executes for the column named Character, the result is an empty table. There is no error message of any kind.

I'm baffled by this. Obviously, my approach is correct otherwise the first and third columns would fail as well. But I can't see anything different about the second column. I'm very new to PHP but know HTML quite well and have substantial experience with Java and a little bit with Perl so I'm not new to programming by a long shot.

Here's the form, which is called Captains_form.php:
Code: [Select]
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/main.css" media="screen"/>
<link rel="stylesheet" type="text/css" href="css/print.css" media="print"/>
</head>
<body>

<h1>Enterprise Captains</h1>

<p>You can view the list of Enterprise Captains in any of the following sequences:</p>

<form action="Captains.php" method="post">
<input type="radio" name="sort" value="Series" /> Series (ascending)<br />
<input type="radio" name="sort" value="Character" /> Character (ascending)<br />
<input type="radio" name="sort" value="Actor" /> Actor (ascending)<br />
<input type="submit" />
</form>

</body>
</html>

Here's the script, which is called Captains.php:
Code: [Select]
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/main.css" media="screen"/>
<link rel="stylesheet" type="text/css" href="css/print.css" media="print"/>
</head>
<body>
<h2>Enterprise Captains List</h2>
<?php 
$con = mysql_connect("localhost:3306","my_All","******");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_Sandbox", $con);

//echo $_POST["sort"];
$SortKey=$_POST["sort"];

$result = mysql_query("SELECT * FROM Captains order by $SortKey");

echo "<table border='1' cellpadding='5' cellspacing='0'>"; 
echo "<tr class='heading'><th>Series</th><th>Character</th><th>Actor</th></tr>";

while($row = mysql_fetch_array($result)) {
  echo "<tr class='detail'><td>" . $row['Series'] . "</td><td>" . $row['Character'] . "</td><td>" . $row['Actor'] . "</td></tr>";  
  }
echo "</table>";

mysql_close($con);
?>

</body>
</html>

Can anyone tell me why the second column, Character, produces an empty result when I select it on the form?

Also, if there is an error message being produced when the query executes, how can I get it? I think I'm handing errors in the connection correctly but I'm not sure how to detect an error in the execution of the query.

The variable is set so the user can see the inside pages of a members area after they have logged in. By the time they go to a different page the variable is gone.

Please note the following:

- It doesn't happen to a specific browser
- It doesn't happen all of the time
- It works when I print the value of the $_SESSION variable
- Once it has been printed to the screen once if I remove the functionality that makes it print, it keeps working.

It's nearly impossible for me to test because I can't recreate the problem. It is my client that has the problem every once in a while.

Please help!!

This might not be enough info for anyone to help with but I'm taking a chance because I'm at my wits end.

I have this relatively simple form on a page called "createquiz.php" which has a select dropdown for every row in the table which triggers the form to submit when an option is chosen.   It is then sent to "move.php" to manipulate the data.   The gist is that  users can go to row 4 (for example) and choose "2" from the drop down menu and it will go to move.php which will then update the id of row 4 to now be 2.  Basically just reordering the rows in the table.

The weird thing is that when the "option" chosen has a value LESS THAN the value of $info['answerid'] for the chosen row, the form submits fine to move.php (like my example above going from 4 to 2.

However, if the "option" chosen has a value GREATER THAN the value of $info['answerid'] for the chosen row (like if the user tried to move row 4 to row 7), the form doesn't submit to move.php and instead the page refreshes with a super weird URL like this...  "createquiz.php?move=3&submitthisform=submit&hidden=move&numanswers=3#".

I have no code anywhere the tries to build a URL anything like that, so something is going very wrong. It looks like it's taking all of the "names" from my form code below and throwing them into a URL.

With this minimal info, just curious if anyone has any idea what type of problem in code could lead to this weird type of URL?

FYI, the code that gets the values for $_GET['quizid'] and $info['answerid'] is not shown, but I'm positive that is all working fine so I don't think it's important in regards to this issue, especially because when the problem happens, it's not even getting to the point where it tries to post to that URL.

Code: [Select]
<form method='post' action='move.php?quizid={$_GET['quizid']}&answerid=" . $info['answerid'] . "'>
<select name='move' onChange='this.form.submit();'>    <option value='x' >Move to...</option> ";
for($i=1; $i<=$lastid;$i++) {
echo "<option value='$i'>$i</option>";
}
echo "</select>
<input type='hidden' name='submitthisform' value='submit' /><input type='hidden' name='hidden' value='move' /><input type='hidden' name='numanswers' value='$lastid' />
</form>

We are able to access Static/Non-static methods with :: operator along with Class name.
What for static in this case?  I am using php5.2.x.  Please give some light on using static in php?


class One{
   function disp(){
      echo " disp here";
   }

       static function show() {
            echo "show here";
      }

}
   One::disp();
        One::show();
