Error handlling if connection couldn't be made

[durlaniulian]

Hello @jsoumelidis ,

Thanx a lot for all your help since now. Now I have a problem when i can't connect to sap via rfc using "sap_connect()". If connection is done i get a resource number, but i don't have the error control when i can't connect: "Fatal error: Uncaught SapConnectionException: LOCATION CPIC (TCP/IP) on local host with Unicode ERROR" When i get this error i want to pop-up an alert with another text.

Can you help me please?

Gratefully, Iulian.

Hi @durlaniulian , You should be able to catch the exception, try something like this:

<?php
try {
    $connection = sap_connect(...);
} catch (SapException $e) {
    //popup alert logic here...
    //or just echo the exception message:
    echo $e->getMessage();
}

Thx a lot. I tried this once but certainly i omitted something.

Do you still have problem? If so, could you paste your code?

[durlaniulian]

No no. It's working. Now I'm trying to figure how can i get the message number to do a case statement.

Sorry for putting all error message but can you help me to extract de message error? (10060 is what i need)

Here is my code: $sapConfig = include DIR . DIRECTORY_SEPARATOR . 'sap_config.php';

try { $connection = sap_connect($sapConfig); } catch (SapException $e) { //popup alert logic here... //or just echo the exception message: $e->getMessage(); var_dump($e); }

[jsoumelidis]

You can use regular expression to extract the info you want from the message, but before doing that, maybe the exception key is enough?

<?php
try {
    $connection = sap_connect(...);
} catch (SapException $e) {
    //Check the exception key
    if ($e->getMessageKey() === 'RFC_COMMUNICATION_FAILURE' ) {
        //popup alert logic here...
    }
    //or just echo the exception message:
    echo $e->getMessage();
}

From this message i want to get only "10060" to be easier for me to show different messages, because this error number can change and i want to show another message.

[jsoumelidis]

You can try regular expressions.

I solved it by other method. I converted the message in string and if his length is bigger than 0 i show another message . Thanks a lot.
