Hi all,

I'm not very knowledgable in apex but I'm learning. I have a form that feeds information into salesforce and creates the Account object when submitted. When a person fills out the form and is required to upload a document, the form outputs a url of that document which populates a URL field in salesforce.

My goal is to save the uploaded documents as an attachment to the newly created Account object.

My issue is that I do not know (if there is way) how to somehow download that file from the form's output URL and save the actual document as the attachment for the Account object.

Also if there if anybody has suggestions on on re-writting the code in a better way, that'd be much aprreciated.

Thanks!

Apex Class:

public with sharing class CreateFileFromAcc {
    public void createFiles (List<Account> accsFromTrigger){ 
       
//The 4 custom fields output URLs
//Signed_EFT__c
//Uploaded_W_9_W_8__c
//COI_TEXT__c
//Signed_MSA__c

       	for(Account currentAccount : accsFromTrigger)    
        {
        Blob txtEft = Blob.valueOf(currentAccount.Signed_EFT__c);
        Attachment attach = new Attachment();
        attach.ParentId = currentAccount.Id;
        attach.Name = currentAccount.EFT_Name__c;
        attach.Body = txtEft;
        insert attach;
        }
        for(Account currentAccount : accsFromTrigger)    
        {
        Blob txtW9 = Blob.valueOf(currentAccount.Uploaded_W_9_W_8__c);
        Attachment attach = new Attachment();
        attach.ParentId = currentAccount.Id;
        attach.Name = currentAccount.W9_Name__c;
        attach.Body = txtW9;        
        insert attach;
        }
   		for(Account currentAccount : accsFromTrigger)    
        {
        Blob txtCoi = Blob.valueOf(currentAccount.COI_TEXT__c);
        Attachment attach = new Attachment();
        attach.ParentId = currentAccount.Id;
        attach.Name = currentAccount.COI_Name__c;
        attach.Body = txtCoi;
        attach.ContentType = currentAccount.COI_TEXT__c;        
        insert attach;
        }
        for(Account currentAccount : accsFromTrigger)    
        {
        Blob txtMsa = Blob.valueOf(currentAccount.Signed_MSA__c);
        Attachment attach = new Attachment();
        attach.ParentId = currentAccount.Id;
        attach.Name = currentAccount.MSA_Name__c;
        attach.Body = txtMsa;        
        insert attach;
        }
    }
}

Apex Trigger:

trigger CreateAccFile on Account (after insert)
{
	for (Account ac : Trigger.New)
	{
		if (ac.RecordTypeId == 'Test')//ACCOUNT RECORDTYPE
		{
	    CreateFileFromAcc cc = new CreateFileFromAcc();
	    cc.createFiles (Trigger.new);
		}
	    else
	    {
	    	createFileFromAcc cc = NULL;
	    }
	} 
}
