com_connect - form and contact mailer

Pat64 · 2019-10-16 17:45:40

Hi all ;)

I would like to select an option based on an URL parameter:

domain.tdl/section?ac=6

How can I achieve such a result with the <txp:com_connect_option /> tag?

What I need: grab the parameter value from the URL, then add a selected attribute to the corresponding choice to show it as a default into the selection list.

Maybe there’s a better way, but your suggestion should work:

Use page_url to grab the “ac” value and put that in a variable, e.g.

<txp_variable name="ac"><txp:page_url type="ac" /></txp:variable>

And then in your com_connect_option tags do:

<txp:com_connect_option label="Option F" value="option-f" 
                        selected='<txp:if_variable name="ac" value="6">1</txp:if_variable>' />

… and so on for each option.

It’s a little verbose but should work.

~~I’m not sure if you need to do any input variable sanitising first, but you could add escape="integer" to the variable tag at the beginning to ensure you get only integers coming through.~~ That’s not necessary: the docs say: “Any other type value will return the matching URL component or the default value that will always be sanitized”.

Hi Jakob ;)

Thank you for your reply.

Unfortunately I can’t get a result.
First of all, the varibale declaration need to be as this:

<txp:variable name="ac" value='<txp:page_url type="ac" />' />

Secondly, it seems that the selected attribut for the com_connect plugin do not return any result:

<txp:php>
echo com_connect_option(array(‘label’=>title(array()),‘selected’=>‘My label’));
</txp:php>

Display a blank selected attribute into the form code souce.

Hmm, I thought both methods – container tag or tag-in-tag attribute – should work.

Not sure if I understood you correctly, but maybe you need to explicitly declare the else case, e.g.

… selected='<txp:if_variable name="ac" value="6">1<txp:else />0</txp:if_variable>' …

What I usually do in such cases, is work through step for step to try and locate the error, e.g.

output the variable first to see if it is actually comes through.
Try the if…else outside the tag-in-tag to see if it the criteria matching works properly.
Try the com_connect_option tag with "1" and "0" values to check if the criteria match property actually produces the desired end result.
Also worth a try: putting the if…else into a variable of its own, then using that as the tag-in-tag so that you’re not trying to do logic inside the tag attribute…

Pat64 · 2019-10-16 21:30:33

Good catch Jakob, you’re right!

The variable statement need a else condition. ;)

For the variable declaration, in my case the tag-in-tag solution did not retrieve any result.

As you said I argue it is verbose but I did not find any more elegant solution…

Thank you lot. I continue to try ;)

Pat64 · 2019-10-16 23:06:19

Ok. It works fine :D

But I need an only one advice because I can’t find how to achieve (and finish) this form.

Because the form is pretty complex, I use the PHP method to declare the options (lot of ones):

global $variable;

echo com_connect_option(array('label'=>'My Label','selected'=>($variable[''ac] == $rs[''ID] ? '1' : '0')));

But unfortunately I have not the selected attribute into my HTML source code (Notice: the variable is populated).

Could you, please, tell me how to set the selected attribute by the variable into the sample code above? Thank you lot by advance for your help.

Pat64 · 2019-10-17 06:26:22

Ok. I changed my code to use some <txp:article_custom /> magic logic instead. :D

I reformulate my demand: how to set the posted attribute to exclude all past publishing until the current date? (I can do that in a Mysql query but not in TXP tags, my bad…)

Ahem… try

<txp:if_variable name="ac" value="6" escape="integer" />

how to set the posted attribute to exclude all past publishing until the current date?

Isn’t that what time="future" does?

Pat64 · 2019-10-17 07:23:30

Thank lot, Oleg!

Strangely, I got better results with time="past" (dealing with date ranges is very enigmatic many times 😱)…

<txp:if_variable name="ac" value="6" escape="integer />

As always, elegant and efficient! 👌🏻

Please, Oleg, accept this golden medal for “The Best Friend of the Day” 🥇

For anyone who want to make some selective options into a com_connect construction, here is the process:

<txp:com_connect_select label="Select a Course (required) *" selected="" break="" class="theme-white" required="1">
	<txp:com_connect_option />

<txp:article_custom section="workshops-retreats" time="past" sort="Posted asc" limit="99">

	<txp:com_connect_option label='<txp:title />' value='<txp:title />' selected='<txp:if_variable name="ac" value=''<txp:article_id />'' escape="integer" />' />

	</txp:article_custom>
</txp:com_connect_select>

Yet another example of much more succinct syntax. So that will work for all attributes that have 1 or 0 (true/false) as an attribute? The same principle as attribute-less attributes is the equivalent of 1?

@Pat, you’re missing some closing quotes after integer in your code above. In your php code, too, you have [''ac] rather than ['ac']. Maybe they were just transfer typos… but if not, that may explain why you weren’t getting what you expected.

All <txp:if_something /> tags without content output 1 (true) or nothing (false). Generally, attribute="" works for most tags, but if you explicitly need 0, you can apply escape="integer" to the empty output.

The same principle as attribute-less is the equivalent of 1?

They are not strictly equivalent, a valueless attribute is evaluated as boolean true, not as 1.

Pat64 · 2019-10-17 08:09:16

etc and Jakob

I noticed variable deals with strings only.

Am I right, Oleg?

Correction: time="future" is the right solution, I just noticed a big difference between my local server (MAMP) and the production linux server! The raison why I always prefer to work on my projects directly within live servers.

Thanks to you two: you save my day!
