<div><Strong>Name: </strong><?= $record['Childvaccination']['name']; ?></div>
When data is not coming then it is showing "Name:" only but I also want to hide name if data is not coming or it is empty.
This is cakephp ctp file.
You want to check if the value is empty or not and output accordingly:-
<?php if (!empty($record['Childvaccination']['name'])): ?>
<div><Strong>Name: </strong><?= $record['Childvaccination']['name']; ?></div>
<?php endif; ?>
I'm using Drupal 7's Solr Search Views module to display my search results.
However, when there are no results, there is no message that displays and i can't figure out how to set one and/or where to find the setting that displays it.
Can anyone help with this?
Thanks.
I've gotten the result I wanted by modifying the 'views-view--viewName.tpl.php' like so:
Original (was not showing anything when $empty or no results):
<?php if ($rows): ?>
<?php print $rows; ?>
<?php elseif ($empty): ?>
<?php print $empty; ?>
<?php endif; ?>
New (shows custom message when no results are found):
<?php if ($rows): ?>
<?php print $rows; ?>
<?php else: ?>
<h2>There are no results for this term. Please refine your search.</h2>
<?php endif; ?>
The big difference is the change from 'elseif ($empty):' to a simple 'else:'.
I want to echo a full name from my MySQL database in my header. When that name is clicked in a list it filters all the records and displays all the records related to that name only. I managed to get the filter working, but not able to display the name in header.
<? $this->read('$jobs as $row'); ?>
<h1><?=$row['Employee']['first_name']?> <?=$row['Employee']['last_name']?>'s Jobs</h1>
<? $this->end(); ?>
If I'm not wrong, you are trying to retrieve this array, I'm assuing $jobs contains single row.
try this
<?php
if (isset($jobs)) {
foreach($jobs as $row){
if (isset($row['Employee']['last_name']))
$last = $row['Employee']['last_name'];
$first = 'N/A';
if (isset($row['Employee']['first_name']))
$first = $row['Employee']['first_name'];
?>
<h1><?php echo $first.' '. $last?>'s Jobs</h1>
<?php } }?>
OR
<h1><?php isset($jobs[0]['Employee']['first_name']) ? $jobs[0]['Employee']['first_name'] : 'N/A' .' '. isset($jobs[0]['Employee']['last_name']) ? $jobs[0]['Employee']['last_name'] : 'N/A'?>'s Jobs</h1>
This can be much more easily achieved through the use of virtual fields. The example in the Cake book is practically identical to your needs.
Just add this to your Employee model:
public $virtualFields = array(
'full_name' => 'CONCAT(Employee.first_name, " ", Employee.last_name)'
);
Now [Employee]['full_name'] can be used without having to use any logic.
Here's the link to the Cake book page covering virtual fields: http://book.cakephp.org/2.0/en/models/virtual-fields.html
I'm using containable to pull associated records into the view action and am getting an error message when looping through results.
Also, I'm using a 'sluggable' behaviour, so the find operation has a condition to search by this variable.
When I debug the find variable in the view, I do see the correct records. But when I try and loop through them in the view I get the 'Notice (8): Undefined index: error.' Ideally I liked to understand how to trouble shoot this error since it happens occasionally.
The model setup is:
tournaments have many tournamentDetails
tournamentDetails have many updates
The records I'm trying to display are:
tournament->tournamentDetails->updates
The tournament controller looks like this:
$tournament = $this->Tournament->find('first', array(
'conditions' => array( 'slug' => $slug),
'contain' => array(
'TournamentDetail' => array(
'Update' => array('order' => 'Update.id DESC'),
))));
The tournament view action looks like this:
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update ['Update']['date']; ?></h3>
<h4><?php echo $update['Update']['title']; ?></h4>
<p><?php echo $update ['Update']['body']; ?></p>
<hr/>
<?php endforeach; ?>
The 'update' data in the view when in debug looks like:
[Update] => Array
(
[0] => Array
(
[id] => 2
[title] => Indoor Challenge
[date] => 2010-03-19
[body] => Congratulations 2010 Champion
[tournament_detail_id] => 4
[homeStatus] => no
)
[1] => Array
(
[id] => 1
[title] => first round matches start today
[date] => 2010-03-19
[body] => this tournament's first round matches start today.
[tournament_detail_id] => 4
[homeStatus] => no
)
Is there something really obvious that I'm overlooking when looping through the 'updates' ?
Thanks, Paul

Thanks everyone for the input. After taking a few steps back it occured to me what was happening with the 'undefined index' and comments about how to loop.
The problem was that the foreach loop wasn't nested, it only looped on the first level of association. The forearch loop deal with 'tournaments' which have many 'tournamentDetails'.
The loop needed to go one level deeper to 'tournamentDetails that have many 'updates'.
Here's the code that resolved this in the view.
<?php foreach ($tournament['TournamentDetail'] as $tournamentDetail): ?>
<?php foreach ($tournamentDetail ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
<?php endforeach; ?>
If others are looking to understand how to use the containable behavior with more than one level of association, just remember that you may have to have nested foreach loops in the view to display the results you're after.
Cheers, Paul
Paul,
given that the other things are right, could it be that you are mixing singular, plural, uppercase and lowercase? In particular the update/updates in various combinations.
Edit 0:
Quick shot?:
There simply is no such index defined, notice that you are working with an array consisting of arrays. It seems you have to use another loop nested in the first.
Edit 1:
Unfortunately, I can only provide quite generic help, as I do not sit infront of your code.
From your post and comments, I would guess that some variable names got mixed up. Just going over the whole dataflow normally does it. What is the exact variable name in the controller which delivers the correct data? If there is one, is it properly set from the controller to the view? Does the view address it correctly.
You are thinking great, this is what I did the last week, but I am quite sure that should do it. Clean out all the view code which currently makes use of any variables from the controller, proceed as described above keeping the dataflow in mind (but do not spend more than one hour on this).
If it does not work:
Something is foobared. Before you spend another week in despair, I would
try it without the containable behavior, see if it works
try to set up exactly the
same scenario in a completely new
CakePHP environment (in your case
1.2.5), see if it works
If you achieve your goals, try to see what went wrong in the original (often a face slapping moment).
If not:
try to see if there is a known bug
consider upgrading (or try to achieve your goals in 1.3.7 first)
Good luck, Benjamin
I think i understand you problem and please Try looping in this way
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
RSK's answer should be right, so since it's still not working you're probably not giving all the information needed. What does this output:
debug($tournament); ?
This all assumes your debug information is debug( $tournament ) and not debug( $update )
/* your old code */
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update ['Update']['date']; ?></h3>
<h4><?php echo $update['Update']['title']; ?></h4>
<p><?php echo $update ['Update']['body']; ?></p>
<hr/>
<?php endforeach; ?>
If the debug value you provided was a debug of the $tournament variable then the first part of your loop simply assigns the numerically keyed arrays inside of the tournaments variable to the $update value.
So, when you send $tournament[ 'Update' ] through the loop you are getting a structure in the $update array like the following.
array(
[id] => 2
[title] => Indoor Challenge
[date] => 2010-03-19
[body] => Congratulations 2010 Champion
[tournament_detail_id] => 4
[homeStatus] => no
)
But in your loop you are trying to access the keyed values as if they exist under an additional layer keyed with 'Update'. That key does not exist in your interior array.
So if my assumption is right - your loop should look like:
/* your old code with edits removing the additional interior Update key */
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
There also seemed to be some spacing in your brackets in the original code - I don't know if this is an issue or not but it looked odd to me.

I have a model named google_news.php which uses the external data, and another model saved_news.php which uses my saved_news table in database,
In my controller I declared that Im using this two models:
var $uses = array('GoogleNews', 'SavedNews');
and my index function reads data:
$this->set('news',$this->GoogleNews->find('all'));
and my view looks like this:
<?php foreach( $news as $newsItem ) : ?>
<?php echo $html->link($newsItem['GoogleNews']['title'], array('action'=>'add', $newsItem['GoogleNews']['title'])); ?>
<?php echo $newsItem['GoogleNews']['encoded']; ?>
<em>
<hr>
<?php endforeach; ?>
How to write the add function in my controller to save each data to my database?
You should assign what you need to be saved into $this->data['ModelName'] as array of fields. Take a look at saving data in the book. That will explain more about the formatting that needs to be followed.
