how to strip a transaction ID out of a string of characters?

11/07/2019 7:56 am | #1 Nathon Jones Web Design

I am migrating data from one system to another and the return from PayPal, in the old system, is being saved into one large text field in the following format. I've changed some details to protect the customer.

{"paypal":{"mc_gross":"65.00","invoice":"de5a339d-ad63-d700-ae2f8b2e-2ed1e56b","protection_eligibility":"Eligible","address_status":"confirmed","payer_id":"PAYERIDHERE","tax":"0.00","address_street":"ADDRESSHERE","payment_date":"04:45:45 Mar 18, 2011 PDT","payment_status":"Completed","charset":"windows-1252","address_zip":"ZIPHERE","first_name":"Nathon","mc_fee":"2.41","address_country_code":"GB","address_name":"Nathon Jones","notify_version":"3.1","custom":"","payer_status":"verified","business":"info@nathonjones.com","address_country":"United Kingdom","address_city":"ADDRESSHERE","quantity":"1","payer_email":"info@nathonjones.com","verify_sign":"ACUe-E7Hjxmeel8FjYAtjnx-yjHAAUeeQSTCtgMMk39U1x4d7hFYcDP7","txn_id":"2MP34045EJ881612V","payment_type":"instant","last_name":"Jones","address_state":"Wigtownshire","receiver_email":"BUSINESSEMAILHERE","payment_fee":"","receiver_id":"Q5Z48PSZEPVC6","txn_type":"web_accept","item_name":"Medical certificate","mc_currency":"GBP","item_number":"1","residence_country":"GB","transaction_subject":"Medical certificate","handling_amount":"0.00","payment_gross":"","shipping":"0.00","merchant_return_link":"Return to Website"},"server":{"REDIRECT_STATUS":"200","HTTP_ACCEPT":"image\/jpeg, application\/x-ms-application, image\/gif, application\/xaml+xml, image\/pjpeg, application\/x-ms-xbap, application\/x-shockwave-flash, application\/vnd.ms-excel, application\/vnd.ms-powerpoint, application\/msword, *\/*","HTTP_ACCEPT_LANGUAGE":"en-GB","HTTP_USER_AGENT":"Mozilla\/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident\/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; OfficeLiveConnector.1.5; OfficeLivePatch.1.3; .NET4.0C; Tablet PC 2.0; InfoPath.2)","CONTENT_TYPE":"application\/x-www-form-urlencoded","HTTP_ACCEPT_ENCODING":"gzip, deflate","HTTP_HOST":"www.sportsmedicalcertificates.co.uk","CONTENT_LENGTH":"1040","HTTP_CONNECTION":"Keep-Alive","HTTP_CACHE_CONTROL":"no-cache","HTTP_COOKIE":"symfony=485f236d39a1bf48c680c7797640721d","PATH":"\/bin:\/usr\/bin:\/sbin:\/usr\/sbin:\/usr\/local\/bin:\/usr\/local\/sbin","SERVER_SIGNATURE":"","SERVER_SOFTWARE":"Apache","SERVER_NAME":"www.sportsmedicalcertificates.co.uk","SERVER_ADDR":"109.123.87.124","SERVER_PORT":"80","REMOTE_ADDR":"86.17.233.9","DOCUMENT_ROOT":"\/home\/medical\/public_html","SERVER_ADMIN":"webmaster@sportsmedicalcertificates.co.uk","SCRIPT_FILENAME":"\/home\/medical\/public_html\/index.php","REMOTE_PORT":"49711","REDIRECT_URL":"\/paypal\/success","GATEWAY_INTERFACE":"CGI\/1.1","SERVER_PROTOCOL":"HTTP\/1.1","REQUEST_METHOD":"POST","QUERY_STRING":"","REQUEST_URI":"\/paypal\/success","SCRIPT_NAME":"\/index.php","PHP_SELF":"\/index.php","REQUEST_TIME":1300448754,"argv":[],"argc":0}}

The new system has separate fields for lots of this data but, in particular, I need to recover the "txn_id".

Is there a script or query that would remove everything either side of "txn_id":"2MP34045EJ881612V" to simply leave 2MP34045EJ881612V?

Thank you.

What are you using to get this string?

This looks like a json string, so you can probably use json_decode() to transform it to an object and then reference the txn_id directly.

If you are using webassist extensions for the transaction, then the TransactionID variable may already be available in the bindings.

Did this help? Tips are appreciated...

The string is what's held/saved in one field of the client's old database table when a PayPal transaction took place. The field is called paypal_response and it's a TEXT type.

They've asked me to port over old orders into their new system which is an absolute ball-ache, but that's what they've asked for.

I am looking for a way to strip out just the data I need to for the new table.

I was trying to get what code is used to get that value. But my previous answer still stands.

I don't know what code is used because it's the client's old website/application built using a thing called Symfony which they can no longer access/use.

What is json_decode() and how do I use it to transform the string to an object?
Also, what is an object?

Are you just trying to update old records? I'm confused at what you are trying to do I guess.

If you are just trying to update the database for existing records to strip out the transaction id, then you could do it by looping through the recordset and updating the existing fields creating a custom php script. This is something I could help with in a premier support ticket.

How are you importing? Through phpMyAdmin?

The easiest way would probably be to import the entire contents and then do a loop with an update after you have the data in your new database.

Hi Ray.

I've got the data in my new database now, and I have fields in the table that are ready for the extracted data that I need.

I've connected to the table with ODBC/MySQL so I can view/edit in Microsoft Access and have been looking at a few String Functions (Left, Right, InStr, Trim) tutorials but I'm slightly weary of running anything.

Is this something you could help me with?
Thank you.
