When I do var_dump, I get the following result:
stdClass::__set_state(array(
'0' =>
stdClass::__set_state(array(
'field' => 'name',
'value' => 'John Smith',
'description' => 'User full name',
))
))
I need the field, value & description in separate string vars.
How do I do this?
I tried:
$field = $obj->field;
$field = $obj->0->field;
$field = $obj->'0'->field;
$field = $obj[0]->field;
$field = $obj['0']->field;
Nothing works!?
Thanks
You can use the curly brace syntax to traverse the object, like so:
$obj->{'0'}->field;
$obj->{'0'}->value
$obj->{'0'}->description
Here is the query string.
$query = "SELECT t.id, t.assignee, t.owner,
d.code, d.status, d.target_completion_date,
d.target_extension_date, d.submission_date, d.approval_date,
d.revision_start_date, d.revision_completion_date, d.message,
ty.name, f.orig_name, f.new_name,
b.payment_date, b.discount, b.total_cost, b.amount_payed, b.edit_level,
b.billing_type, b.pages, b.words
FROM tasks t
INNER JOIN details d ON t.detail_id = d.id
INNER JOIN billing b ON t.billing_id = b.id
INNER JOIN TYPE ty ON d.document_type_id = ty.id
INNER JOIN files f ON t.file_id = f.id
WHERE t.assignee = 'argie1234'";
And this is the array i would like the query result to turn into.
$user = array('allTask'=>array(array('taskid' => 1,

How can i create the above array? I sure know how to define multi dimensional array, regretfully though i am having difficulty creating this complex array dynamically. As a beginner i don't even know where to begin.
Here is an example that might help you out. Try starting with simple multi dimensional arrays, once you get a hold of it, you can move onto building complex ones. You will then find that the array you want to build is not really difficult than you initially thought it to be.
$mycomplexarray = array('key1' => array('val1', 'val2'),
'key2' => array('val3', 'val4' => array('val5', 'val6')
)
);
You could create the array just as you have here. I'm not gonna write the whole thing out, but something like this...
$result = $mysqli->query($query); // however you query the db is up to you.
$row = $result->fetch_assoc(); //same as query use your prefered method to fetch
$user = array('allTask'=>array(array('taskid' => $row['id'],
'assignee'=>$row['assignee'],
'owner'=>$row['owner'],
'details' => array( 'code' => $row['code'],
'status'=>$row['status'],
...etc, Hope this makes sense for you.
Set up a structure array first that defines which columns will be stored in a sub array like
$struc=array('Id'->0, 'assignee'->0, 'owner'->0,
'code'->'detail', 'status'->'detail', 'target_completion_date'->'detail',
'target_extension_date'->'detail', 'submission_date'->'detail', 'approval_date'->'detail',
'revision_start_date'->'detail', 'revision_completion_date'->'detail', 'message'->'detail',
'name'->'file', 'orig_name'->'file', 'new_name'->'file',
'payment_date'->'billing', 'discount'->'billing', 'total_cost'->'billing', 'amount_payed'->'billing', 'edit_level'->'billing', 'billing_type'->'billing', 'words');
In your while ($a=mysqli_fetch_assoc($res)) loop you can now use this structure to decide whether you want to store an element directly in your target array or whether you want to place it in the subarray named in this structure array. Like
$res=mysqli_query($con,$sql);
$arr=array();
while($a=mysqli_fetch_assoc($res)) {
// within result loop: $a is result from mysqli_fetch_assoc()
$ta=array(); // temp array ...
foreach ($a as $k => $v){
if ($struc[$k]) $ta[struc[$k]][$k]=$v;
else $ta[$k]=$v;
}
$arr[]=$ta; // add to target array
}
This is the complete code, no more is needed. It was typed up on my iPod, so it is NOT tested yet.
The generated array should be equivalent to your $user['allTask'] array.
i have the array here.
http://pastebin.com/i5ZUQNm6
and this from php result.
$result1 = $mo->find(
array(
'username' => 'BLABLA',
'stream' => array('$exists' => true)
)
);
foreach ($result1 as $obj) {
print_r($obj);
}
how i sort the [stream] child and limit it to 1 result? and how to find [id_stream] child?
thanks
To limit, to a single document
use limit(1):
$result1 = $mo->find( array(
'username' => 'BLABLA',
'stream' => array('$exists' => true) ) )->limit(1);
or
findOne
$result1 = $mo->findOne( array(
'username' => 'BLABLA',
'stream' => array('$exists' => true) ) );
And to sort the child.
You need to also add at the end ->sort(array("stream.time" => -1));
I've seen the pastebin, and I guess you want to order by date.
Final code:
$result1 = $mo->findOne( array(
'username' => 'BLABLA',
'stream' => array('$exists' => true)))->sort(array("stream.time" => -1));;
From what I know for limiting to a single value of the array you need a loop
you need to add (inside the find, just after the main array): find(.... , array('streams' => array('$slice' => 1)));
Using a combination of sort and limit should work - the code in slownage's answer looks like it may be what you need.
i am sending an ordered json_encode list of some MySQL tables, from php, but when i retrieve it with jquery it is not in order any more? everything works fine and in order on the php side. it's the client side that i'm having trouble with. i think the problem is that i'm sending a multidimensional array from php as json. what would be the most efficient solution? also why has the order changed when retrieved by jQuery.
PHP CODE:
$user_data = array();
while($row = mysql_fetch_array($retval, MYSQL_ASSOC){
$user_id = $row['user_id'];
if(!isset($user_data[$user_id]){
$user_data[$user_id] = array(
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'dept' => $row['dept'],
'quals' => array()
);
}
$quals = array(
'qual_cat' => $row['qual_cat'],
'qual' => $row['qual'],
'count' => $row['count']
)
$user_data[$user_id]['quals'][] = $quals;
}
echo json_encode($user_data);
jQuery:
$.post('page.php', function(post){
$.each(post, function(i,data){
alert(data.first_name+' '+data.last_name+' - '+data.dept);
});
});
PHP VAR_DUMP:
array
10 =>
array
'first_name' => string 'David' (length=5)
'last_name' => string 'Dan' (length=3)
'dept' => string 'web' (length=3)
'count' => string '5' (length=1)
'quals' =>
array
0 =>
array
...
1 =>
array
...
2 =>
array
...
3 =>
array
...
4 =>
array
...
In php, array is by default associative, so that's why you have this behavior as associative array order is not guaranteed (as per explanation in the link given by benedict_w).
To overcome this, you could try the following:
echo json_encode(array_values($user_data));
This will effectively turn your json from
["10":{prop1:val1, prop2:val2}, "25":{prop1:val1, prop2:val2}]
into
[{prop1:val1, prop2:val2}, {prop1:val1, prop2:val2}]
If you need to keep track of the id, put it inside your user_data in your php:
if(!isset($user_data[$user_id]){
$user_data[$user_id] = array(
'id' => $user_id,
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'dept' => $row['dept'],
'quals' => array()
);
}
how do I build a find() query in cakePHP using these conditions:
Find where
MyModel.x = 1 and MyModel.y = 2 OR
MyModel.x = 1 and MyModel.y value does not exist (or is equal to empty string)
Can somebody tell me how I can go about building such find query?
I'm gonna give you some pointers, but you need to try to do this as it's very basic and it's always good to practice.
A basic find in cake is in the form of
$this->ModelName->find('all');
This in its default form does a SELECT * from model_names (convention is to have singular ModelName for plural table name - model_names)
To add conditions:
$this->ModelName->find('all', array('conditions' => array('ModelName.x' => 1));
To add AND conditions
$this->ModelName->find('all', array('conditions' => array(
'ModelName.x' => 1, 'ModelName.y' => 2
));
To add OR conditions
$this->ModelName->find('all', array('conditions' => array(
'OR' => array(
'ModelName.x' => 1, 'ModelName.y' => 2
)
));
To combine both
$this->ModelName->find('all', array('conditions' => array(
'ModelName.y is not' => null,
'OR' => array(
'ModelName.x' => 1, 'ModelName.y' => 2
)
));
// where y is not null and (x = 1 or y = 2)
http://book.cakephp.org/1.3/view/1030/Complex-Find-Conditions
(btw I'm sure there will be users giving you the exact answers, so just take my answer for your reference :) )
$this->MyModel->find('all', array('conditions' => array(
'OR' => array(
array(
'MyModel.x' => 1,
'MyModel.y' => 1
),
array(
'MyModle.x' => 1,
'OR' => array(
array('MyModel.y' => NULL),
array('MyModel.y' => '')
)
)
)
)));
