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.

Hi, i am using history.back() method to go back to previous page. the problem is data i entered in the page is not retain when i click back button. whats the problem. thanks in advance. -sun

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

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"; } } //class ?>

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

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"

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 -sun

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?? thanks in advance -sun

Hi, thanks for your reply. Is there any other way to access the web service on different domain. i tried to access with "xmlhttprequest", but even then getting same problem var xmlhttp; function validateIPAddress1(sysName) { url="http://sunil/misc/misc.asmx/isIP?IPaddress=" +sysName; xmlhttp=null; if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else if (window.ActiveXObject) { // code for IE5 and IE6 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } if (xmlhttp!=null) { xmlhttp.open("GET",url,true); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4) { var myXml = xmlhttp.responseXML; var xmlobject = null; var XMLText = null; if (window.ActiveXObject) { XMLText = myXml.childNodes[1].firstChild.nodeValue; alert(XMLText); } else { XMLText = myXml.childNodes[0].firstChild.nodeValue; alert(XMLText); } } } xmlhttp.send(null); } else { alert("Your browser does not support XMLHTTP."); } } any suggestions??? thanks in advance -sunil

Hi, I have designed a form with text box for reading IP address and onChange method of textbox i am calling a javascript function to validate IP address entered in the textbox. In java script function, i am invoking a web service developed in C# which is on different domain. when i am running this page getting the warning message "This page is accessing information that is not under its control. This poses a security risk. Do you want to continue?" my java script function is: <CODE> function validateIPAddress(sysName) { var ret; var QueryString = "http://sunil/misc/misc.asmx/isIP?IPaddress=" +sysName; var xmldoc=new ActiveXObject("Microsoft.XMLDOM"); xmldoc.async = false; xmldoc.load(QueryString); oNodeList = xmldoc.documentElement.childNodes; ret = oNodeList.item(0).text; if( ret == "BAD_ADDRESS") return false; else return true; } </CODE> Could any one shed some light on this.

do we need to configure anything in php.ini for Teradata? if so, could you let me know the configurations that need from PHP side thanks, -sunil

Thanks for your reply. teradata ODBC driver is already installed on my system and able to connect to teradata with DSN. with Teradata ODBC driver, we even can't connect with DSN. any suggestions?? thanks, -sunil

any suggestions on this?

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 -sunil
