Creating my first module, module doesn't display, hook function isn't executed, no errors.

[amando96]

So I've been following prestashop's tutorial on how to make modules, it works fine in the backoffice, I can set variables, etc.

 

But it simply will not show in the front office, I'm using the default bootstrap theme, and prestashop 1.6.

 

I added echos and die() in the hookDisplayLeftColumn(), but they didn't affect anything, it's like it isn't even being executed.

 

I did everything exactly like the tutorial says, I don't know why this isn't working.

 

The hook is registered in the database.

 

I get no errors, no logs, nothing.

 

Any ideas? Problem is exactly like this, but there was no solution there.

show your code please

your module is correctly hooked to displayLeftColumn ?

Sorry about no indentation.

 

ignore the test variable, I deleted parts of it but it didn't work when it was okay either, so that isn't it.

i checked this on my own installation

everything works

 

make sure that:

- your module is attached to displayLeftColumn hook under modules > positions tab in back office

 

in addition, make sure that your left column is enabled!

[amando96]

I still don't get what I'm expecting(the TPL output), what exactly did you try/get?

 

Edit: Added the hookDisplayFooter method and transplanted it, works fine, as far I understand the LeftColumn is active in the themes tab...

[vekia]

module is properly hooked to the column hook, 

when im browsing front office it informs me that there is no .tpl file

so if you will create .tpl file (as I did) it will appear instead of message about missing template.

[amando96]

Doesn't here, when hooked to the left column nothing happens.

[vekia]

i know that sounds weird but... have you got left column?

[amando96]

The theme options say I do, does the default-bootstrap have a left column?

[vekia]

yes it doesnt have, for example, on homepage there is no left column by default.

can you show screenshot of page where you're trying to check it?
