I have these tables:
xml_documents table that has just one column, which is id
master_information table that has these columns id, xml_document_id, container, next_page
the relationship is one to one.
everything is working on my model. I can add, update, delete and every thing is working perfectly.
now I want to export my model as xml.
so I need to transfer my xmlDocument model to an array, then transfer this array to xml. I can do the second part myself, which is transfering php array to xml, but I don't know how to transfer the model to an array.
I tried this:
$xmlDocument = XmlDocument::find(4)->get()->toArray();
dd($xmlDocument)
but I got all the xml_document rows like this
array(2) { [0]=> array(1) { ["id"]=> int(4) } [1]=> array(1) { ["id"]=> int(5) } }
Then I tried this:
$xmlDocument = XmlDocument::find(4)->toArray();
dd($xmlDocument)
but I got this:
array(1) { ["id"]=> int(5) }
I need to also get the relationship. for example:
Array (
[id] = 4
[xmlInformation] => Array (
[id] => 1
[container] => 'bla'
[next_page] => 'bla bla'
)
can you help please?
Try this;
For a specific XmlDocument;
XmlDocument::with('MasterInformation', <... comma separated list of other relationships>)->find(4)->toArray();
For all XmlDocuments;
XmlDocument::with('MasterInformation', <... comma separated list of other relationships>)->get()->toArray();

How to sort the following array?
I have an multidimensional array that gets filled with total hours for each brand
$totalHours = array(
'brand' => array(),
'project' => array(),
'hours' => array()
);
The output is something like this (project is not filled):
array(3) {
["brand"]=>
array(3) {
[0]=>
string(4) "Nike"
[1]=>
string(9) "Coke Cola"
[2]=>
string(8) "Converse"
}
["project"]=>
array(3) {
[0]=>
string(6) "Bonobo"
[1]=>
string(4) "LDRU"
[2]=>
string(2) "US"
}
["hours"]=>
array(3) {
[0]=>
int(28)
[1]=>
int(106)
[2]=>
string(1) "2"
}
}
Now I would like to sort the array based on the "hours" field.
I've tried the array_multisort but it seems like I simply don't get how this function works and how to apply it to this array.
I have been able to sort an single array with just one row of values. If I apply that to this problem im sorting only the hours field, leaving the others unsorted and therefore the array is corrupted.
The "project" does actually contains a string. It always does. In this example I didn't filled it.
array_multisort should work:
$totalHours = array(
'brand' => array('Nike', 'Coke Cola', 'Converse'),
'project' => array(),
'hours' => array(28, 106, '2')
);
array_multisort($totalHours['hours'], $totalHours['brand']);
var_dump($totalHours);
That data format is not very convenient because there is no direct association between brands and hours, they even sit in different arrays! Plus, the last hour is a string, not an integer.
We're going to have to create an intermediate array to associate them and sort them. We'll then re-inject everything in the original array.
// Make sure both arrays of brands and hours and the same size
if (count($totalHours['brand']) != count($totalHours['hours'])) {
throw new Exception('Invalid data!');
}
// Make sure every hour record is an integer, not a string
$totalHours['hours'] = array_map('intval', $totalHours['hours']);
// array_combine will sort all arrays based on the sorting of the first one
array_multisort($totalHours['hours'], $totalHours['brand'], $totalHours['project']);
EDIT: Using array_multisort was #delprks 's idea originally. Here I applied it to both brand and project arrays.
You cant do that with a single array_* function!
if (project is not filled) always and the indexes of brand and hours are equal, then you can do:
$forsort = array_combine($totalHours["brands"],$totalHours["hours"]);
asort($forsort,SORT_NUMERIC);
$totalHours["brands"]=array_keys($forsort);
$totalHours["hours"]=array_values($forsort);
But, this is just an answer for you question, not best practise at all.
I have this code for an array, and the problem is that it shows only two last items of the array.
$svi= array(
$WMN1,
$LNG1,
$SSWN1,
$DT1,
$OET1,
$OW1,
$NT1
);
$imena_sajtova = array(
'Prvi WMN',
'Drugi LNG',
'Treci SSWN',
'Cetvrti DT',
'Peti OET',
'Sesti OW',
'Sedmi NT'
);
$novi_svi =array_combine($svi, $imena_sajtova);
echo '<pre>'; print_r($novi_svi); echo '</pre>';
And the result of this code is:
Array
(
[2] => Sedmi NT
[1] => Sesti OW
)
What could be a problem? Thanks!
var_dump($svi) displays this:
array(7) { [0]=> int(2) [1]=> int(1) [2]=> int(1) [3]=> int(1) [4]=> int(2) [5]=> int(1) [6]=> int(2) }
This $svi array has results from some functions:
$WMN1=RSS_Brojac($WMN);
$LNG1=RSS_Brojac($LNG);
$SSWN1=RSS_Brojac($SSWN);
$DT1=RSS_Brojac($DT);
$OET1=RSS_Brojac($OET);
$OW1=RSS_Brojac($OW);
$NT1=RSS_Brojac($NT);
I've changed order of arrays in the array_combine, and it works!
$novi_svi =array_combine($imena_sajtova, $svi);
arsort($novi_svi);
echo '<pre>'; print_r($novi_svi); echo '</pre>';
And the output of this code is:
Array
(
[Prvi WMN] => 2
[Sedmi NT] => 2
[Peti OET] => 2
[Sesti OW] => 1
[Cetvrti DT] => 1
[Drugi LNG] => 1
[Treci SSWN] => 1
)
I'have sorted them from high to low, that's what I actually wanted to do with this array.
Now, how to separate the results, to have them in separate divs inside html?
So then, I'll be able to change their style and create some kind of table with these results.
The results are output from some RSS feeds, which I use to count number of published news.
Thank you for your time!
Well there you go, the exact reason why you only retrieve two values after the array combine is because you've only supplied two unique integers, 1,2 as the indexes of the arrays to be combined. You need at least 7 unique values for your 7 strings.
Here's an example using your code and it doesn't work
And...Here's an example using 7 unique indexes, that does work
Typecast the values in the first array before merge. Can be achieved with array_map(). I assume you know the desired types in the variables.
We upload a lot of photos to WordPress. We do not use them all though. The unused ones remain "attached" to the post it's not in which makes it hard to go back and delete it.
I've build 2 arrays. One array contains all of the images from the post content ($postImages). The other array contains all of the images WordPress database have attached to the post ($mediaImages).
I'm trying to identify which images appear in the database, but not in the post. This way I can detach the image from within the database.
I'm using array_diff to compare the two arrays, however it's not showing the odd man out. It appears to be showing the matches.
Here's my arrays:
Call this one $postImages:
var_dump($postImages);
array(3) {
[2]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog1.jpg"
[0]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog2.jpg"
[1]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog3.jpg"
}
And $mediaImages:
var_dump($mediaImages);
array(4) {
[1]=>
array(1) {
[0]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog1.jpg"
}
[2]=>
array(1) {
[0]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog2.jpg"
}
[0]=>
array(1) {
[0]=>
string(64) "http://mywebsite.com/wp-content/uploads/2013/11/photoblog3.jpg"
}
[3]=>
array(1) {
[0]=>
string(62) "http://mywebsite.com/wp-content/uploads/2013/12/IMG_0069.jpg"
}
}
Here is the output:
$matches = array_diff($postImages, $mediaImages);
print_r($matches);
Array
(
[2] => http://mywebsite.com/wp-content/uploads/2013/11/photoblog1.jpg
[0] => http://mywebsite.com/wp-content/uploads/2013/11/photoblog2.jpg
[1] => http://mywebsite.com/wp-content/uploads/2013/11/photoblog3.jpg
)
Expected output:
Array
(
[0] => http://mywebsite.com/wp-content/uploads/2013/12/IMG_0069.jpg
)
As Marc B pointed out in the comments, $mediaImages is an array of arrays of strings, while $postimages is just an array of strings.
You can use array_map() with a custom callback to create the $mediaImages array:
$mediaImages = array_map(function($item) {
return $item[0];
}, $mediaImages);
Also, note that you have the parameters for array_diff() backwards. The correct order is:
array_diff($arrayToCompareFrom , $arrayToCompareAgainst);
So to compare $postImages against $mediaImages, you'd need:
$matches = array_diff($mediaImages, $postImages);
print_r($matches);
Demo.
I want to store 2 dependent values in this array:
["STEP5"]=> array(1) {
["OPTIONS"]=>
array(2) {
[0]=>
string(4) "opt2"
[1]=>
string(4) "opt3"
} }
Option fields (opt1, opt2,...) can have an extra field input. So how to store that in my array ? Thanx a lot.
You make each element of the OPTIONS array into an array itself. This would be better illustrated as:
["STEP5"] => array(1) {
["OPTIONS"] => array(2) {
[0] => array(2) {
["TEXT"] => "opt2"
["INPUT"] => "input data"
}
[1] => array(1) {
["TEXT"] => "opt3"
// No input data here
}
}
}
Then you can access the fields as:
$foo["STEP5"]["OPTIONS"][0]["TEXT"]
$foo["STEP5"]["OPTIONS"][0]["INPUT"]
$foo["STEP5"]["OPTIONS"][1]["TEXT"]
You don't have to have the "INPUT" field for every single option, but you can add it if you need to. Also, you might consider using objects to accomplish this task as they provide lots of useful functionality.
I would like to push an associate array into another array but I an not sure how to go about it. At the minute I have the following:
$rate_info = array(
"hotel_rating" => $hotel->{'hotelRating'},
"room_rate" => $hotel->{'RoomRateDetailsList'}->{'RoomRateDetails'}->{'RateInfo'}->{'ChargeableRateInfo'}->{'#total'},
"currency" => $hotel->{'RoomRateDetailsList'}->{'RoomRateDetails'}->{'RateInfo'}->{'ChargeableRateInfo'}->{'#currencyCode'},
"deep_link" => $hotel->{'deepLink'}
);
array_push($hotel_array[$hotel->{'name'}]["offers"], "expedia" => $rate_info );
"Offers" is an array , all I want to do is add an key value with an array within in. Any ideas? All I seem to be getting at the minute is parse errors.
UPDATE
This is the output of the array so far
["offers"]=>
array(2) {
["LateRooms"]=>
array(4) {
["hotel_rating"]=>
int(4)
["room_rate"]=>
string(6) "225.06"
["currency"]=>
string(3) "USD"
}
[0]=>
string(4) "test"
}
As you can see instad of [0] I would like ["site"]=>array()
Thanks
Oliver
I'd do this for the array assignment:
$hotel_array[$hotel->name]['offers']['expedia'] = $rate_info;
Ensure your warnings are enabled, so you know arrays (and subarrays) have been set up before you use them.
Did you first do this?
$hotel_array[$hotel->{'name'}] = array();
And then you can do:
array_push($hotel_array[$hotel->{'name'}]["offers"], "expedia" => $rate_info );
