SID-02106: Populate Form with links issued from a Search

Status:	Answered	TWiki version:	6.0.1	Perl version:	5
Category:	CategoryForms	Server OS:	RedHat	Last update:	10 years ago

Hi all. I am working on my knowledge base and I am stuck with an improvement I want to make. First, my knowledge base is set up as this support web : topics are created with a pre-defined name, for example KmPrj00001 for a project or KmLes00001 for a lesson learned.. ect the proper name is defined in the formfield "Name"

Right now when the user want to create a lesson learned, he has to fill in a text box for the projects linked to that lesson.

What I am trying to do is:

1- propose a list (using the intelligible name from formfield "Name") from a search of all projects for the user to pick in the creation process

2- pass to the form a link to that project : something like [[KmPrj00001][ formfield "Name"]

What I have done : 1- I managed to have my form looked at the list of project in the form of links :

| !Project | select+multi | 10 | %SEARCH{ search="^KmPrj[0-9]+" nonoise="on" order="%URLPARAM{ "order" default="modified" }%" reverse="%URLPARAM{ "reverse" default="on" }%" scope="topic" type="regex" format=" [[$topic][$formfield(Name)]]," }% Other to be created! | Project concerned | |

2- using VarEDITFORMFIELD, I then loose the link and then it doesn't match the form...

I wonder if it is not the good way to do it.. but the good thing is when you edit the topic you can choose from the different links.

I tried another way bay passing the link from the creation page :

Project during which we learned a lesson%BR%<select name="test1"><option>%URLPARAM{"test1"}%</option><option>%SEARCH{ search="^KmPrj[0-9]+" nonoise="on" order="%URLPARAM{ "order" default="modified" }%" reverse="%URLPARAM{ "reverse" default="on" }%" scope="topic" type="regex" format="<option > $formfield(Name) </option>" }% <option>Other to be created!</option></select> 
<input type="hidden" name="Project" value="%URLPARAM{ "test1" default="nothing" }%"  />

it is not working either. Any suggestions?

Discussion and Answer

Not sure I understand your question, but it looks like you want a dropdown where the submitted value is different from the displayed value.

1. If you use a TWiki Form and want to present to the user this dropdown, use type select+multi+values. Details at TWikiForms

2. You can create a hand-crafted HTML form with a dropdown:

<select name="Project">
<option value="">Select...<option>
%SEARCH{
 search="^KmPrj[0-9]+"
 nonoise="on"
 order="%URLPARAM{ "order" default="modified" }%"
 reverse="%URLPARAM{ "reverse" default="on" }%"
 scope="topic"
 type="regex"
 format="<option value=\"$topic\">$formfield(Name)</option>"
}%
</select>

Thanks Peter, the hand-crafted HTML is close to what I need. I want the value to be a link to the topic using the intelligible name. Something like :

format="<option value=\" [[$topic][$formfield(Name)]]\">$formfield(Name)</option>"

but this is not working.

How about reworking the app? I think it is better not to store the full link in the form field. That way the Name field is not duplicated and can't get out of sync. Better to store just the topic name, and then in the report compose the proper link using VarFORMFIELD to look up the Name.

ok, so i though again about it and reworked it that way :

• when the new topic is created, the user browse through a list of project using explicit names: $topictitle

• the real topic is stored in the form in the format KmPrj00...($topic)

• the header is then doing the translation into an explicit link.

There is one thing missing though: father and child handling. I want to use the parent functionality to link topics together. I just need to create a button on each topic enabling the user to change the parent from a list of $topictitle... any thoughts on how I can do that?

Create a form with action="/cgi-bin/save/Support/SID-02106" method="post" attributes, containing a select with dynamic options as discussed before. Use name='topicparent' attribute for the select.

Thanks, I changed it to

<form name="new" action="%SCRIPTURLPATH{save}%/%BASEWEB%/%BASETOPIC%" method="post">

and now it works

-- Sebastien Digard - 2015-10-05

Indeed. better to use the SCRIPTURLPATH variable for the action attribute.
