Keeping form values in tact when returning errors

Recommended Posts

Hello,

When submitting a form to another page or itself and an error is returned (either by FM or verification code), is there an easy way to keep what the user had filled in in-tact when reloading the form page to display the error/message..besides using sessions?

Thanks for your help!

Yes and No.

PHP maintains several predefined variables. Three which are relevant here are: $_POST, $_GET, and $_REQUEST. ($_REQUEST contains $_GET + $_POST + $_COOKIE);

They are associative arrays using the name attribute from the elements on the submitted form as keys to the elements' values. You can use these to repopulate your form on a submit error. A simple trick is to have the form submit to the same page. If the submission is successful then show the successful submission HTML; if the submission fails show the form.

The one caveat is that PHP does use sessions to maintain these variables. It manages the sessions so there is no need to worry about calling session_start(), but it does require cookies so that it can grab the session id from the client.

Thanks for the reply. That makes sense....

If I understand correctly, I would preload the form fields with $_REQUEST['formfieldname'] - which wouldn't show on initial load but would once they submit, POSTing those variables, and reload the form with an error and submitted information.

Does that sound about right? Or would that throw an error on the initial load?

That will throw a warning; do this:

<?

$field1 = isset($_REQUEST['field1'])?$_REQUEST['field1']:"";

?>

<?

Side note to Mods:

the code tags are still stripping ?> from code this makes them somewhat problematic for displaying code that switches between php and html

      I am working on an API integration from FileMaker 17 to Emma. Generally when I work on a new API, I get the curl working on the command line and then translate that into FM. But I've hit a roadblock with one particular API call while my other API calls to Emma are successful. (In the example below, I substituted out sensitive data with all caps.)
      From the command line, the code is:
      curl -u USER:PASS -H "Accept:application/json" -H "Content-type: application/json" -X POST -d '{"fields": {"name_first": "TESTFIRST","name_last": "TESTLAST","eligible": "false","expiration": "@D:2019-06-30"},"group_ids": ["GROUPIDNUMBER"],"email": "EMAIL@EMAIL.COM","opt_in_confirmation": "false"}' "https://api.e2ma.net/ACCOUNTNUMBER/members/signup"
      This command is successful.  The server responds with the individuals' emma id and group confirmation. 
      This fails using Insert from URL within FM though. While eventually I'll use FileMaker fields for an individual record's names, email, and expiration dates, I did not use fields in my testing in order to duplicate the command line exactly. In Insert from URL:
      The URL is "https://api.e2ma.net/ACCOUNTNUMBER/members/signup"
      The curl option is "-u USER:PASS -H \"Accept:application/json\" -H \"Content-type: application/json\" -X POST -d '{\"fields\": {\"name_first\": \"TESTFIRST\",\"name_last\": \"TESTLAST\",\"eligible\": \"false\",\"expiration\": \"@D:2101-06-30\"},\"group_ids\": [\"GROUPIDNUMBER\"],\"email\": \"EMAIL@EMAIL.COM\",\"opt_in_confirmation\": \"false\"}'"
       
      Can anyone identify the problem or suggest a workaround? My experience with API integration with FM is limited, but anything I could get working via the command line, I've been able to get working within FM until this.

      Hello,
       
      I am trying to connect to our current database with our shipping company so I can update the status of the delivered orders. To do that, I am currently using insert from URL and then parse the code to extract the info I need. However, I believe there should be a cleaner and safer way to do it using webservice.
      So I downloaded the documentation and looks very straightforward to set and I have been able to set up the POST and send it getting the data as XML using POSTMAN (as very well explained here:  http://www.filemakerprogurus.com/filemaker-api-integration-salvatore-coleangelo/ ) and also in the great post by luminfire https://luminfire.com/2017/06/12/curling-filemaker-16/.
      However, when I try the same parameters on my script in filemaker, I get all the time an error saying that something like  "Entry XML Schema/template it is not loaded correctly". Following the documentation of the API I see that on Postman I need to insert on the Body RAW some kind of code that looks like this: 
      <?xml version='1.0' encoding='UTF-8'?>
      <SeguimientoEnviosRequest xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='SeguimientoEnviosRequest.xsd'>
      <Solicitante>x</Solicitante><Dato>xxxxxxxxxxxxxxxxx</Dato>
      </SeguimientoEnviosRequest>
      but I don't know which settings I have to do on my script to make the call work.
      Any suggestions as to where to put this info so the can be passed with the CURL? I am a bit desperate now because I see the amazing possibilities that the interaction with the web service may bring but I can find a way to make it work...
      Thanks a lot for your always invaluable support!!

      Hi,
      I want to enable the Cloud REST API, but I am afraid that I "dismissed" the notification message that allowed me to do so. How can I enable the RESP API on my cloud instance?
      Thanks,
      -J

      OK, I'm using FM16 and trying to figure out an API call.  I'm not an expert when it comes to APIs.
      I have a shopify store, and I can use Insert from URL to get the JSON info on each order.  I want to be able to "PUT" and upload parts of the order.  Every order has a "Note" field that I can add notes.  Per the shopify API documentation, to add an order note, you do the following:
      Add Note to order
      PUT /admin/orders/#{id}.json { "order": { "id": 450789469, "note": "Customer contacted us about a custom engraving on this iPod" } }  
      Can someone help me with what I put in the cURL options area?  Any help would be appreciated.  I think I have the URL and Target figured out.  Thank you!!
