Has anyone had success integrating the Javascript API (4.6) with Drupal 7x?

StevePeralta — Tue, 13 Mar 2018 16:04:22 GMT

I was getting a "dojo.js:24 Error: multipleDefine" and then I moved "<script defer src="https://js.arcgis.com/4.6/"></script>" to just before </body>. It got rid of the error, but my map still wasn't showing up. I was bringing in the map Javascript from a separate js file.

I wrote a custom Drupal module to handle it all.

Any help appreciated.

Okay, I will answer my own question after a few days of toiling over this. Drupal 7 is not friendly to the DOM and blasts it from left and right with all kinds of stuff, so the key is to get the Esri scripts and your custom scripts loaded at the same time which, for Drupal, means in the same file. There are other ways of doing this, but not without a lot of Drupal headaches. So!

1. Create your Drupal module. I created a module called "find_my_leg" which is short for "Find My Legislator." Directory/file structure looks like this:

modules/custom/find_my_leg
modules/custom/find_my_leg/find_my_leg.info
modules/custom/find_my_leg/find_my_leg.module
modules/custom/find_my_leg/theme
modules/custom/find_my_leg/theme/theme.inc
modules/custom/find_my_leg/theme/js/findmyleg.js
modules/custom/find_my_leg/theme/templates
modules/custom/find_my_leg/theme/templates/find_my_leg_page.tpl.php

2. Write your map code. The only three files I'll provide code for here are "find_my_leg_page.tpl.php", "findmyleg.js," and "find_my_leg.module." The others are out of the scope of this post. Check Drupal 7 docs for more info.

find_my_leg_page.tpl.php

<script defer src="/sites/all/modules/custom/find_my_leg/theme/js/findmyleg.js"></script>
<!-- Replace these with your own styles -->
<style>

main#main-content.main-content{

margin-top: -50px;
}

#viewDiv {

}

}

And that is it! I'm super new to Esri so there are some things to improve on here, I'm sure, but hope you get some use out of it.
