In FileMaker I have (a.o.) two related tables, where Betreuer_id of table "studentpaper" refers to id of table "Betreuer".
With help of FileMaker's PHP API, I want to access a record in "studentpaper" including the releated fields. Howerver, the later poses a problem. Consider the following PHP code:
$findCommand =& $fm->newFindAllCommand('studentpaper');
$result = $findCommand->execute();
$records = $result->getRecords();
$record = $records[0];
echo $record->getField('Titel'); // okay
echo $record->getField('Betreuer_id'); // okay
echo $record->getField('Betreuer::Name');
// ERROR: get empty string, even related record has a non-empty field
I have expected for "Betreuer::Name" the correct related result, as usually in FileMaker (and as I get in studentpaper's layout). However, I get only an empty string.
What am I doing wrong? Does the relation in FileMaker's PHP-API differs from the "usual" FileMaker approach?
In case anybody is interested, I found the solution on my own.
The problem was that the field wasn't defined (in the layout) as normal text input, but as selection field resticted by a value list.
Thus, one needs to access the value not via the usual getField function but by one of the functions related to value lists. In my case, getValueListTwoFields did the job.

As part of a search routine for a specific crop, I'm making two calls to the same database table, merging the results and sending them down the line. The first call looks for data relating to the searched-for crop (e.g. "beans"). The second call looks for data relating to the crop group of that crop (e.g. legumes).
Data returned from the first call will be more relevant/focused than that from the second call. I want to add an identifier to the respective data sets that reflects this so that I can subsequently sort/present the data on the basis of relevance in my Vue component.
The following code extracts the crop-specific information from the database; how can I add/insert/append a new variable (e.g. "relevance" = 1) to each row in $factsheets before I "array_merge" it with the data returned from the crop-group sql call?
(For sake of simplicitly, I've not included the code that determines the crops.id value from the name of the crop entered by the user.)
public function getFactsheets($cropId){
$factsheets = Factsheet::whereIn('crop_id',$cropId)
->join("crop_factsheet as cf","factsheets.id","=","cf.factsheet_id")
->join("crops as crops","crops.id","=","cf.crop_id")
->select('crops.name','title', 'factsheets.id', 'shortdesc', 'shortimg', 'factsheets.slug')
->orderBy('crops.name')
->get()->toArray();
return $factsheets;
}
Thanks, Tom.
If you give & to value so whatever changes will happen to value will directly saved on its address.
foreach($factsheets as $key => &$factsheet){
$factsheet['relevance'] = 1;
}
Working demo.
Here is concise explanation of references in official doc.
you can simply do a foreach
foreach($factsheets as $key => $factsheet){
$factsheet['relevance'] = 1;
}
I'm developing a tool for a website and I came up with an odd problem, or better, an odd situation.
I'm using the code bellow to retrieve data from the TeamSpeak server. I use this info to build a profile on a user.
$ts3 = TeamSpeak3::factory("serverquery://dadada:dadada#dadada:1234/");
// Get the clients list
$a=$ts3->clientList();
// Get the groups list
$b=$ts3->ServerGroupList();
// Get the channels list
$c=$ts3->channelList();
Now, the odd situation is that the output of this code block:
// Get the clients list
$a=$ts3->clientList();
// Get the groups list
$b=$ts3->ServerGroupList();
// Get the channels list
$c=$ts3->channelList();
echo "<pre>";print_r($a);die();
(Notice the print_r)
Is totally different from the output of this code block:
// Get the clients list
$a=$ts3->clientList();
// Get the groups list
#$b=$ts3->ServerGroupList();
// Get the channels list
#$c=$ts3->channelList();
echo "<pre>";print_r($a);die();
What I mean is, the functions I call after clientList() (which output I store in the variable $a) are changing that variable's contents. This is, they're kind of appending their output to the variable.
I've never learned PHP professionally, I'm just trying it out... Am I missing something about this language that justifies this behavior? If I am, what can I do to stop it?
Thank you all.
You're seeing parts of the "Object" in Object Oriented Programming
$ts3 represents an Object containing all the information needed, along with some methods (or functions) that let you get data from the object. Some of these methods will do different things to the object itself, in order to retrieve additional data needed for a particular method call.
Consider the following simple Object:
Bike
color
gears
function __construct($color, $gears)
this.color = $color; this.gears = $gears
function upgrade()
this.headlight = true; this.gears = 10;
Now, when you first create it, it only has two properties:
$myBike = new Bike('red',5);
// $myBike.color = 'red';
// $myBike.gears = 5;
...but once you upgrade, properties have changed, and new ones are added.
$myBike->upgrade();
// $myBike.color = 'red';
// $myBike.gears = 10;
// $myBike.headlight = true;
Objects usually pass references rather than copying data, in order to save memory.
...but if you want to make sure that you're getting a copy that won't change (i.e. does not use data references to the $ts3 object), clone the variable.
$a = clone($ts3->clientList());
Be warned, this will effectively double the memory and processor usage for that variable.
I have a database with a table called translations. It has several columns, but I am trying to create a session array to house a variale:translations named array.
I've tried the below code, but I must be missing something... my end goal is to populate much of the static verbiage of a website using $_SESSION['TRANSLATIONS']['Userboards'] for example to populate the names of otherwise static content into any language supported based on the database.
$querylang = "SELECT variable,translation FROM translations left outer join languages on languages.abbrev = translations.fkabbrev WHERE languages.abbrev = 'EN'";
$sqllang = mysql_query($querylang);
while($reslang = mysql_fetch_array($sqllang)){
$_SESSION['TRANSLATIONS'][$reslang['variable']] = $reslang['translation'];
};
The above code is actually correct. The reason it didn't work was a separate issue. Thanks to #Epodax for reminding me to check the errorlog!
A bit of weird issue - I am looking to enter data into two separate
collections (same db) and I am getting totally weird results. I am
sure it is the way I am doing this but it is the results which have me
a bit baffled.
Here is a snippet of what I am trying to accomplish:
$mynewconnection = new Mongo(); // create new mongo connection
$collectionDB = $mynewconnection->Datadb; // select db
$collectionA = $collectionDB->DataA; // select collectionA
$collectionB = $collectionDB->DataB; // select collectionB
/* Go off and chop up data and create CriteriaA/B */
$insertA = $collectionA->insert($criteriaA);
$insertB = $collectionB->insert($criteriaB);
So what I am trying accomplish is to enter part of the data set into
one collection and the other part of the dataset into another
collection. What is happening is that sometimes the data will be
entered into Both collections (as desired) and other times data will
be entered into just collectionA and yet other times data will be
entered into just collectionB.
Anyone have any ideas on what I am missing or what would be causing
this strange behavior?
When you fire a query to write something to MongoDB, it does not confirm whether the data is written to database or not. You need to see the page of php's manual for Write Concerns.
The link for the same is: http://www.php.net/manual/en/mongo.writeconcerns.php
I have a mySQL database table setup called site.
Rather than qet the column headings to produce a PHP object of values I want to produce data from the rows.
TABLE: site
:::field:::::value:::::
url www.example.com
name example site
etc Example Etcetera
So I want to be able to get this information from the server by calling the column name I want and the row I am after. I want to do this for all fields in site as I don't want to do multiple calls for the various different rows in site; I'd rather store all the information from the beginning in the object:
eg. <? echo $site['url']; ?>
I created this put it appears to be causing an error:.
$sql = "SELECT * FROM `site`";
$site[];
foreach($sodh->query($sql) as $sitefield){
$site[$sitefield['field']] = $sitefield['value'];
}
Obviously I've missed something. ¿Any idea as to what?
$site[];
should be
$site = array();
