Zoho Creator: Sendmail a list of attachments

: Joel Lipman; Zoho; 20 July 2023; Hits: 3573

What?
This is a very quick article on sending an email with Deluge which needs a dynamic number of files attached to it.

Why?
This came up during a call with another developer and it occurred to me that perhaps this isn't clearly documented. But there are tips found across the web just not specifically addressing this.

How?
Here is the code for a test function which downloads 2 files from a public domain, no user wall. The key here which the official documentation is missing is the .setParamName() but for those who have spent time to find this function, they'll already know this.

void fn_Joel_Test()
{
	/***
		- tried with getUrl() but this doesn't work.
		- has to be an invokeUrl
		- set param name required
		- if file comes from a Creator form, no InvokeURL needed
			c_Form = Form[ID == 1234]; 
			r_Download1 = c_Form.myFieldWithFile;
	***/
	l_Downloads = List();
	r_Download1 = invokeUrl
    [
    	url: "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf"
    	type: GET
    ];
	r_Download1.setParamName("file");
	l_Downloads.add(r_Download1);
	r_Download2 = invokeUrl
    [
    	url: "https://www.africau.edu/images/default/sample.pdf"
    	type: GET
    ];
	r_Download2.setParamName("file");
	l_Downloads.add(r_Download2);
	//
	sendmail
    [

    	to: "This email address is being protected from spambots. You need JavaScript enabled to view it."

    ]
