i have an array, something like
[0] => Array
(
[id] => 1
[name] => Jimmy
[address] => Array
(
[number] => 1
[street] => Astreet
)
)
I need to access [street] using something like helper array_get dot notation:
array.address.street
However, as it can have multiple elements, I need something like
array*
where it can just get the first one.
Coming from cakephp they have a helper so i can do
array.{*}.address.street
Is there something similar in laravel, i cannot find such
If you want to get street from the first element you can do:
array_get(head($array), 'address.street');
// or
array_get($array, '0.address.street')
And if you want to get list of elements that contains street you can use array_pluck:
array_filter(array_pluck($array, 'address.street'));
$addresses = array_map(function($obj) {
if ( array_key_exists('address', $obj) )
if ( count($obj['address']) > 0 )
return $obj['address'][0];
}, $yourArray);

In laravel 5.4 when validation is failed I do like:
if ($validator->fails()) {
$errors_list = $validator->messages()->all();
and I got array like :
[errors_list] => Array
(
[0] => The image has already been taken.
[1] => The is main has already been taken.
)
What I dislike in this output that actuall name of error field is ommitted.
Code
echo '<pre>$validator->messages()::'.print_r($validator->messages(),true).'</pre>';
has output:
$validator->messages()::Illuminate\Support\MessageBag Object
(
[messages:protected] => Array
(
[image] => Array
(
[0] => The image has already been taken.
)
[is_main] => Array
(
[0] => The is main has already been taken.
)
)
[format:protected] => :message
)
And I did not find how access to messages data.
I would like to get array like:
[errors_list] => Array
(
[image] => The image has already been taken.
[is_main] => The is main has already been taken.
)
Is there is a way to make it ?
Thanks!
I hope this will work for you.
$errors->has('image');
$errors->get(image);
$errors->has('is_main');
$errors->get(is_main);
It's a tricky one. The reason it's like that is because there may be multiple validation errors happening at once. However if you only have a single rule per entry:
array_combine($validator->messages()->keys(),$validator->messages()->all())
how to get the values of multidimensional array.
code//
Array
(
[0] => Array
(
[City] => Array
(
[title] => Nagpur
[id] => 20299
)
[Branch] => Array
(
[0] => Array
(
[id] => 8
[country_id] => 41
[state_id] => 102
[city_id] => 20299
[title] => Geotech Services Ltd.
)
)
)
[1] => Array
(
[City] => Array
(
[title] => kolapur
[id] => 20300
)
)
)
Here I want to get the only values if cities(title) so plz tel me how to fetch in cakephp..
Thanks in advance
Thus you finding as recursive so all related data is fetched with City.
To disable this recursion, you need to set $recursive = -1;
You can do this by many ways--
place $this->City->recursive = -1; before find operation
place recursive => -1 on find overation
Globally set public $recursive = -1; on AppModel.php
And if you read from this array its simple and basic programming operation...
foreach($cities as $city){
echo $city['City']['title']
}
using cakePHP what you're trying to do is usually achieved using Hash
Assuming $your_array contains the data, then you have to do:
$cities = Hash::extract($your_array, '{n}.City.title');
I got a Joomla ticketing module, that displays at a certain part of the page, the current tickets of the current user. I want to create user groups, in which the group members can view all of the tickets belongin to that group. I thought the easiest way is to create Joomla groups, assign the users to those, and to when a user loges in, it can see all of the tickets in its group. I added my code to the start of the function, but something is wrong... For every user (currently the "Registered" ones) displays the same result, that of the last users tickets, and I don't know why: Here is the code:
function gTickets()
{
$user =& JFactory::getUser();
$user_id = (int) $user->get('id');
//get user_group_id from db based on current users id
{...}
//get all users with that user_group_id
$db1->setQuery($db1->getQuery(true)
->select('*')
->from("#__user_usergroup_map")
->where("group_id = '$groupss'")
);
$groupss1=$db1->loadRowList();
$return1=array();
// for every user_id
foreach ($groupss1 as $keya)
{
$user_id = $keya[0]; // the id of users
$where = "";
if ($this->is_staff)
$where .= " AND t.`staff_id`='".$user_id."'";
else
$where .= " AND t.`customer_id`='".$user_id."'";
$tickets = $this->_getList(
"SELECT t.id, t.subject, t.last_reply_customer, s.name AS status_name FROM
#__rsticketspro_tickets t LEFT JOIN #__rsticketspro_statuses s ON
(t.status_id=s.id) WHERE 1 $where ORDER BY `last_reply` DESC", 0,
$this->params->get('tickets_limit', 3));
print_r($tickets);
return $tickets;
}
I got some questions, that I didn't know how to seach for...
what is the letter dot fieldname in the sql query? eg:
SELECT m.ticket_id, m.message FROM #__ticket_messages m WHERE m.user_id !='".$user_id."
what does the "m" mean before the WHERE?
what does the "1" do here: WHERE 1 $where
Also, I looked in the ACL managers, but could not make it work with this code.
Edit: Thanks for the fast answers! I got 1 more, and I think it's an easy one, but I can't get it to work...
If I print the content of the $ticket array into another array, I get an array with multiple arrays. That is why my code is not working... The array i'm getting is:
Array (
[0] => stdClass Object (
[id] => 1
[subject] => use1
[last_reply_customer] => 1
[status_name] => open
)
)
Array (
[0] => stdClass Object (
[id] => 3
[subject] => use2
[last_reply_customer] => 1
[status_name] => open
)
[1] => stdClass Object (
[id] => 2
[subject] => use2
[last_reply_customer] => 1
[status_name] => open
)
)
I would like the array to look like this:
Array (
[0] => stdClass Object (
[id] => 1
[subject] => use1
[last_reply_customer] => 1
[status_name] => open
)
[1] => stdClass Object (
[id] => 3
[subject] => use2
[last_reply_customer] => 1
[status_name] => open
)
[2] => stdClass Object (
[id] => 2
[subject] => use2
[last_reply_customer] => 1
[status_name] => open
)
)
Thanks!
Edit: is all of this complicated to achieve?
Look into ACL to get that part working, but to answer the 3 questions you posted at the bottom of your question:
1) the letter.field_name in the query represents the table alias.field_name in the query. The alias (m) makes it easier so you don't have to keep typing the full table name each time.
2) The m before the WHERE is actually setting the table alias, but with lazy syntax. It should say:
SELECT m.ticket_id, m.message FROM #__ticket_messages AS m
3) The "WHERE 1" is the SQL way of saying "if (true)". Since they are immediately appending the $where clause afterwards "WHERE 1 $where", the resulting query looks like this:
WHERE 1 AND t.staff_id = '" . $user_id . "'
Did you code this originally? or is it a component that you picked up somewhere? It should be using the query builder instead of direct SQL like it currently is, to make it more portable and more clear as to what it is doing.
I have the following line in my controller:
$data['faq'] = $this->faqModel->get();
This data print the following using the print_r
Array
(
[faq] => Array
(
[0] => Array
(
[faqid] => 12
[catid] => 122
[question] => How this CMS works
[question_en] => How this CMS works
[answer] => How this CMS works?
[answer_en] => How this CMS works?
[sorder] => 2
[visible] => 1
)
[1] => Array
(
[faqid] => 8
[catid] => 121
[question] => How does the design cost?
[question_en] => How does the design cost?
[answer] => How does the design cost?
[answer_en] => How does the design cost?
[sorder] => 1
[visible] => 1
)
)
)
I want to use the value stored in the [catid] key, and I am trying to do something like:
$data['faq']['catid'] to get that value in the controller (I want to make another select with that value) But I am getting with this error message: Undefined index: catid
Anyone can help me to get the value of ['catid']???
Regards, Zoran
Its 3 dimensional array u look closely there is two elements in faq array. You must wrote something like this: $data['faq'][0]['catid'] or $data['faq'][1]['catid']
The way you are accessing the array is incorrect, you are missing the item index on the second level. The correct way to use it as you are doing would be to do
echo $data['faq'][0]['faqid']; //faqid of the first item
However, this will only show one faqid at a time, and it not so useful when you are iterating. So, a good way would be this way.
foreach($data['faq'] as $value) {
echo $value['faqid'];
}

I need to print all, only of 1 villa (example with id = 6) but VillaId is not an array so it's impossible to get all with foreach
I can obtain it with:
echo 'Name of Villa: '.$xml->Villa[0]->VillaName.'';
etc. etc ... but in this way have to change manually for every villa (too much) the value in the brackets.
i've tried with $xml->Villa[$value]->VillaName; ($value comes from another page) but it's not working...
Tanks for help!
First of all, your question starts with "i have this xml:" followed by something that is not XML. I'm not saying this to be a smartass, rather because it's important for XML beginners to understand that print_r() is not the right way to inspect SimpleXMLElements. Sometimes it will show you things that aren't in your XML, other times it will not show things that are actually in your XML. In short: do not use print_r() on SimpleXMLElement. Just use ->asXML() and look at the actual XML.
From what I understand, you want to locate and select a node based on some criteria. XML just happens to have a language for that: XPath. The official specs aren't terribly user-friendly but w3schools.com has a pretty good XPath tutorial.
I need to print all, only of 1 villa (example with id = 6) but VillaId is not an array so it's impossible to get all with foreach
Anywhere in your document, you want to select all Villa nodes with an attribute VillaID whose value is "6". In XPath:
//Villa[#VillaID="6"]
Via SimpleXML:
$xml->xpath('//Villa[#VillaID="6"]');
Attention, xpath() always return an array.
