Tableselect in forms issue
Hi All I am trying to use tableselect in forms as per below code. * $form['category_boundary']['category_fieldset']['catg'] = array ( '#type' => 'tableselect', '#header' => $header, '#options' => $options, '#multiple' => TRUE, '#js_select' => FALSE, ); * By manipulating options array, I can add the rows in forms table. Sometimes I need to remove the selected rows from form table. My question is, how can I determine if a particular row is selected. Currently using below code to determine which row is selected. * foreach($form_state['values']['category_boundary']['category_fieldset']['catg'] as $key => $value) { if($form_state['values']['category_boundary']['category_fieldset']['catg'][$index]
0) { //row is selected. } else { //row is not selected. } }* ** I can determine all the rows if those are selected or not except the 0th row. Can somebody tell me, what is the RIGHT way to determine if a particular row in a table is selected or not.
Best Regards Kamal
Seems like it should work provided you really meant $index to be $key. That's not in your real code, right? If it is in your cod that way, that's the bug. ________________________________ From: support-bounces@drupal.org [mailto:support-bounces@drupal.org] On Behalf Of Kamal Palei Sent: Thursday, September 13, 2012 5:32 AM To: support@drupal.org Subject: [support] Tableselect in forms issue Hi All I am trying to use tableselect in forms as per below code. $form['category_boundary']['category_fieldset']['catg'] = array ( '#type' => 'tableselect', '#header' => $header, '#options' => $options, '#multiple' => TRUE, '#js_select' => FALSE, ); By manipulating options array, I can add the rows in forms table.

Shouldn't it be greater equal zero to get the first element? On Thu, Sep 13, 2012 at 8:13 AM, Metzler, David <metzlerd@evergreen.edu>wrote:

Hi All Thanks a lot for the input. I am little bit confused with* $index *stuff. When I add tableselect element, I use the key "*['category_boundary']['category_fieldset']['catg']*" . Somewhere deep in form code, for every row's checkbox, what index is used by form.inc I really do not know. So instead of *$index* what I should use, I am not sure. Tried to debug more. When I am trying to add rows (means *none* of the rows were selected), if I print the array using dpm(), I get below output. ... (*Array, 4 elements*) - 0 (*Integer*) *0* - 1 (*Integer*) *0* - 2 (*Integer*) *0* - 3 (*Integer*) *0* When I am tying to delete rows (means one or more rows were selected, in this particular case I had selected rows 2, 3 and 4), if I print the array * $form_state['values']['category_boundary']['category_fieldset']['catg'] * using dpm(), I get below output, ... (*Array, 4 elements*) - 1 (*String, 1 characters *) *1* - 2 (*String, 1 characters *) *2* - 3 (*String, 1 characters *) *3* - 0 (*Integer*) *0* Thats the reason, thought of taking *$index* as key where $index can be one of 0,1,2,3. Using the logic mentioned in my first email, I will be able to delete the rows 2, 3 and 4. But the problem is if I try to delete the 1st row it does not get deleted. I tried to print the array, it looks as below. ... (*Array, 4 elements*) - 0 (*String, 1 characters *) *0* - 1 (*Integer*) *0* - 2 (*Integer*) *0* - 3 (*Integer*) *0* Since irrespective of fact, 0th row is selected or not, always value is 0. Thats the reason, why logic (*if($form_state['values']['category_boundary']['category_fieldset']['catg'][$index]
0) *) does not work. But from above prints, one thing is clear while I have selected 0th row, 0th element is 0 (*String, 1 characters *) *0* and when 0th row is not selected, it looks as 0 (*Integer*) *0* , (please note the difference here) hence, there should be someway to determine if 0th row is selected or not. I am not a PHP expert , so probably missing something here.
Can somebody kindly help here, how do I determine if the 0th row is selected or not. Best Regards Kamal Net Cloud Systems, Bangalore On Thu, Sep 13, 2012 at 11:35 PM, Metzler, David <metzlerd@evergreen.edu>wrote:

There is probably a more correct way to do what you want but I don't have time to research it so I'm just answering based on your data. if ($myarray[0] === 0) { $myarray_0_isset = FALSE; } else { $myarray_0_isset = TRUE; } -- Earnie -- https://sites.google.com/site/earnieboyd
You are struggling with some basic php concepts. I'm guessing your $options array contains integers as the value and the 0th element of the array is a '0'. which is the crux of the problem. '0' > 0 will always return false. Perhaps the comparison that you need to write write is !== 0. the extra = sign in php comparisons means exactly equal in both type and value. Otherwise the '0' string data gets converted to the 0 integer before the comparison. My point about $index vs. $key was really about your code snippet: foreach($form_state['values']['category_boundary']['category_fieldset'][ 'catg'] as $key => $value) { if($form_state['values']['category_boundary']['category_fieldset']['catg '][$index] > 0) { //row is selected. } else { //row is not selected. } } In this code "as $key => $value" means that the array index will be placed in the variable $key, but then you're using an undefined variable $index in the $form_state['values'] test. $index is an undefined variable as far as I can tell, but I'm betting it get set by code that you omitted to keep the example sanely short. Sometimes though when people post these they just haven't noticed, so I wanted to point it out. In short changing y our >0 comparison to !==0 should solve the problem. ________________________________ From: support-bounces@drupal.org [mailto:support-bounces@drupal.org] On Behalf Of Kamal Palei Sent: Thursday, September 13, 2012 5:42 PM To: support@drupal.org Subject: Re: [support] Tableselect in forms issue Hi All Thanks a lot for the input.
