[problem in using history.back()]

 

thanks for your reply. my problem is, I have designed a form which takes data like name, contact number, e-mail etc from users. if users enter wrong e-mail and submit the form, it validates the form data and gives "back" link to correct wrongly entered data.

Incorrect e-Mail address. Please go <a href="javascript:history.back();">back</a> and enter the e-Mail address correctly

 

when i click the "back" link, all of the form data was gone. how can i make retain the form data when clicked the back link.

 

data is retained when going through browser's back button. but not with javascript:history.back method

 

any ides??

 

 

thanks again.

My intension is to write a PHP class for handling errors. thats why i am developing the "Error" class which has a constructor in which i am setting up the user defined error handler and a "ErrorHandler" method which handles all errors encountered while execution.

 

please help me in this regard

 

 

thanks in advance

[Error handling]

 

This is my actual class:

 

<?php
class Error
{

    function __construct (){
    {
	if (error_reporting() == 0)
		return;

	//set_error_handler(array($this,"ErrorHandler"));
	set_error_handler("ErrorHandler");
    }
  
    function ErrorHandler($errno,$errstr,$errfile,$errline)
    {

	$errorType = array (
		   E_ERROR          => 'ERROR',
		   E_WARNING        => 'WARNING',
		   E_PARSE          => 'PARSING ERROR',
		   E_NOTICE         => 'NOTICE',
		   E_CORE_ERROR     => 'CORE ERROR',
		   E_CORE_WARNING   => 'CORE WARNING',
		   E_COMPILE_ERROR  => 'COMPILE ERROR',
		   E_COMPILE_WARNING => 'COMPILE WARNING',
		   E_USER_ERROR     => 'USER ERROR',
		   E_USER_WARNING   => 'USER WARNING',
		   E_USER_NOTICE    => 'USER NOTICE',
		   E_STRICT         => 'STRICT NOTICE',
		   E_RECOVERABLE_ERROR  => 'RECOVERABLE ERROR'
	);


	$errtime=date("Y-m-d H:i:s (T)");
	$err_message="An error occured on ".$errtime."\n";
	$err_message .="Details are as follows\n";
	$err_message .="Error Number : $errno\n";
	$err_message .=$errstr."\nOccured in ".$errfile."\n";
	$err_message .="On Line $errline \n\n";
	$err_message .=str_repeat("-",50);
	$err_message .="\n";

[Error handling]

thanks for your reply.

 

In my "Error" class i have constructor and ErrorHandler() method.

 

Class: Error

    constructor

    ErrorHandler

 

i changed the constructor code to set user defined error handler to Error Class method "ErrorHandler"

 

set_error_handler("ErrorHandler");

 

even then i am getting the warning msg:

 

Warning: set_error_handler() expects the argument (ErrorHandler) to be a valid callback in C:\php_dev\errorHandler\sun_error.php on line 16

 

 

 

thanks in advance

[Error handling]

 

As far as i know, i am using set_error_handler inside the class , i am passing the array. If we use the set_error_handler out side the class, then its enough to mention the "error handler"

[Error handling]

Hi,

  I am writing a PHP class for custom error handling. In constructor i am setting up the error handler like this.

    function __construct (){
    {
	if (error_reporting() == 0)
		return;

	$this->logger = new Logger("mylog.log","append") ;  //create object to logger class
	set_error_handler(array($this,"ErrorHandler"));        //set user defined error handler
    }

 

while running the i am getting below warning:

 

Warning: set_error_handler() expects the argument (Error::ErrorHandler) to be a valid callback in C:\php_dev\errorHandler \sun_error.php on line 16

 

 

what is this waring? can any one tell me how can i remove this warning??

 

thanks in advance

[user defined error handling]

Hi,

  I am planning to write a PHP class for handling Errors/Warnings using trigger_error function.  Could any one explain what happens the below line gets executed?

 

    trigger_error("SQL:Non Timeout Error", E_USER_NOTICE);

 

I know we can process it using our own error handler with set_error_handler(). but  if didn't set user defined handler, what happens then? will it reporterror??

[Teradata connection with PHP]

 

any suggestions on this?

[Teradata connection with PHP]

I am able to connect to Teradata using DSNless connection in windows but failing in Linux.

my code is

  function ConnectDB($host, $username, $password, $options="") {

	$con_string = "DRIVER={Teradata};DBCName=" . $host ."; DATABASE=DBC; RunInQuietMode=Yes";

        if (!($this->connection_id = @odbc_connect($con_string,$username,$password)) ){

                 $this->report_error("\nConnection Failed.....\n");

                  exit;

         }

         else {

                 echo "\nConnected to ". $host. " DB..."."\n";

                  return $this->connection_id;

         }


        }//end of connectDB

[/Code]

 

The above code is working fine in Windows but resulting below errors in Linux

  ODBC error: [DataDirect][ODBC lib] Invalid string or buffer length

  ODBC error code: S1090

 

I think we can use odbc_connect() function for both DSN and DSNless connections. As per my knowledge,

odbc_connect() when used with DSN connection, calls SQLConnect(). But when used with DSNless connection calls SQLDriverConnect(). 

 

But when i checked my driverTrace, i observed that odbc_connect in linux calling SQLConnect() eventhough i am passing DSNless connection string.

 

could any one help in this regard.

 

thanks in advance
