i have dictionary like
$request = {"Url":"localhost","Database Name":"hotel","Database User":"admin","Password":"a"}
now i want to fetch value of each key so how to this one is possible with Joomla code.
If any one know please reply me fast.
Thanks in advance.
Try this,
Its a json encoded value,
$str = '{"Url":"localhost","Database Name":"hotel","Database User":"admin","Password":"a"}';
$ar = json_decode($str);
echo "<pre/>";
print_r($ar);
The result will be
stdClass Object
(
[Url] => localhost
[Database Name] => hotel
[Database User] => admin
[Password] => a
)
Hope its helps..

I want to except empty value field from $request->all();
Array ( [first_name] => Dev 1 [password] => [last_name] => [phone] => 123456 [password_confirmation] => )
I got the array like this but I want to except field from above array like last_name, password which has no value.
Any way to do this without for loop.
I mean laravel provide any default method for that ?
Thanks
array_filter will remove empty elements:
$filtered = array_filter($request->all());
I am attempting to output a CSV from a query result. dbutil->csv_from_result() should work, but it only returns the column headers. No data is included.
I tracked it down to system/database/DB_utility.php which uses unbuffered_row().
Any calls to unbuffered_row() return NULL. If I change it to row(), I get a result. It makes no difference if I use unbuffered_row('array') or unbuffered_row('object')
Why does row() work but unbuffered_row() does not?
Is this a bug in CI or am I missing something?
Edit: row('array') doesn't seem to work either.
Edit: It seems that calling $query->result() spoils dbutil->csv_from_result($query). You apparently cannot iterate through query results AND then save the results in a CSV file. This was possible in CI 2.
Is there any way to show query results AND save the CSV without running the query twice?
I have faced similar problem and found this:
I have this query:
$query = $this->db->query("SELECT * FROM tablename");
print_r($query);
Then I get this and unbuffered_row works fine:
CI_DB_oci8_result Object
(
[stmt_id] => Resource id #106
[curs_id] =>
[limit_used] =>
[commit_mode] => 32
[conn_id] => Resource id #91
[result_id] => 1
[result_array] => Array
(
)
[result_object] => Array
(
)
[custom_result_object] => Array
(
)
[current_row] => 0
[num_rows] =>
[row_data] =>
)
BUT if I call $query->num_rows() before I get a different CI_DB_oci8_result object and unbuffered_row didn't work returning null
$query = $this->db->query("SELECT * FROM tablename");
echo $query->num_rows();
print_r($query);
Hope this help somebody.
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())
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 am following nettut+ tutorial for pagination and to store POST inputs as querystrings in db. So far, everything works fine until, suppose if I get an array as POST input, i am unable to loop through it and get all the array values and to store into query_array (i.e., store array within array).
The snippets below:
$query_array = array(
'gender' => $this->input->post('gender'),
'minage' => $this->input->post('minage'),
'maxage' => $this->input->post('maxage'),
'Citizenship' => $this->input->post('citizenship'), // checkboxes with name citizenship[]
);
This returns only last stored array value in Citizenship.
The output array:
Array ( [gender] => 1 [minage] => 18 [maxage] => 24 [Citizenship] => 2 )
makes the query string as:
&gender=1&minage=18&maxage=24&Citizenship=2
But, my requirement is to get all the values of 'Citizenship' array instead of last stored value.
The output required to make query string:
Array ( [gender] => 1 [minage] => 18 [maxage] => 24 [Citizenship] => 2 [Citizenship] => 4 [Citizenship] => 6 )
The query string :
&gender=1&minage=18&maxage=24&Citizenship[]=2&Citizenship[]=4&Citizenship[]=6
Any help appreciated..
Thanks.
Doesn't look like code ignighter supports un-named multidimensional arrays as input without a bit of hacking.
If you can access raw $_POST data try replacing
$this->input->post('citizenship')
with
array_map('intval',$_POST['citizenship'])
Alternativly add keys to your post data:
&gender=1&minage=18&maxage=24&Citizenship[0]=2&Citizenship[1]=4&Citizenship[2]=6
I fixed it myself. I just looped through the POST array and got the individual array key & pair values.
foreach($_POST['Citizenship'] as $k => $v) {
$Citizenship[$v] = $v;
}
Hope this helps someone who face similar problem.
