Custom profile fields empty, if/else

[mysticrystal]

So basically what I'm trying to do is make it where if a custom profile text  field is not entered then it will just show the number 0. But everytime I try with the code below, it adds 0s everywhere or just doesn't work. I might just be dumb but I really need some help please. 



{foreach $[user.mini_custom_field]}{if $[user.mini_custom_field.name] == "MP"} $[user.mini_custom_field.value]
{else} 0 {/if}{/foreach}

[CrazyBoy]

I suggest to move {foreach ...}{/foreach}
So it won't let the 0 appear each time I hope

[mysticrystal]

Move it where?

[CrazyBoy]

You want all the custom fields to have this option or only for the "MP" custom field ?

[mysticrystal]

CrazyBoy only the MP custom field

So why you are using the if statment of that name between {foreach}{/foreach} tags ?

[mysticrystal]

Because I have to say which custom field is being used? I know I'm not good at this which is why I'm asking for assistance.

I still asking also. But this os fine
From the code I see it says. Each time you see custom field and if a name is MP else set to 0. Which you may set to 0 before the else
This causes problems
I currently with phone untill 19 so I can test a code in my mind

I'm sorry, but I don't know what you mean. If you can help me with the code, please do whenever possible. If not, thank you and hopefully someone else is able to help me.

This isn't currently possible to achieve.

When a custom field hasn't been filled out in your profile settings it's not included in the array of objects the foreach loop goes through, so none of the if statements included inside the loop will ever see it.

For example, if you have custom fields named A, B, and C and you only fill out A and C in your Edit Profile page this foreach loop will only output the names of fields A and C:

{foreach $[user.mini_custom_field]}
    <br>Field name: $[user.mini_custom_field.name]
{/foreach}

Result:

Field name: A
Field name: C

Field B was never filled out, so it was never included in the loop.

Brian Okay thank you.

You can sort of work around this by using CSS and if/else.

I'd have to dig into it more when I'm at home, but basically you can put text inside a div or a span with a class name surrounded by if/else tags, eg:

<span {if $[user.mini_custom_field.name] == "Field C"}style="display: none;"{/if}>0</span>

Then style="display: none;" will appear only if the condition is true. If the field doesn't exist, it can't match the IF condition and will therefore display the 0. If it does exist, it will hide the 0.

[mysticrystal]

Kami Whenever you get the chance to dig into it more, please let me know. I tried to use the code but it always says 0.

I think Kami's suggestion works under the assumption that the foreach loop is going to run for every field. But because the loop ignores fields that aren't filled out it runs into the same problem as before.

You can get around all of the issues presented so far through the use of JavaScript to add new elements to the page when one that you specify is detected as missing, but then you're using JavaScript and running code for every post on the page. JavaScript has to do all of its calculations client-side and do the heavy lifting on the member's computer so it might increase page rendering time. But it'd work!

you could still do this with if/else, you would just have to get really granular with the custom fields. I have a working example on another forum so i'll pop that in here over the weekend (:
