I have a site developed in codeigniter and I have a model where I have to create two Json but I don't know if is better to save it into my server or pass it itno the controller and after in the view but how?
This is my model simplify:
public function calledFromController(){
//code...
$this->makeRequest();
}
public function makeRequest(){
//code...
foreach ($foo as $foo2){
$values[] = $foo2->value;
}
foreach ($hello as $hello2){
$values_hello[] = $hello2->value;
}
//save it into my server
$file = fopen('foo.json','w+');
fwrite($file, $foo);
fclose($file);
$file2 = fopen('hello.json','w+');
fwrite($file2, $file2);
fclose($file2);
}
Now I save it, but can be a very lot of data and after I have to open each json and parse it into javascript (backbone).
Is better this mode or return this two json (I have to mantain separate Json)?
Is I have to return this two Json how Can I do?
From my controller I call the function calledFromController in the model.
Try by creating an array and returning the array if you want to return both the json:
$data = array();
$data['foo'] = $foo;
$data['hello'] = $hello;
return $data;
In the controller:
$return = $this->model->function();
$foo = $return['foo'];
$hello = $return['hello'];

I'm trying to get an array_merge but I can't. Calling the example.php file must also embed the array of the Usage_Module function.
Note: The getFunctionModule function must not be changed.
Surely I'm wrong something in the Usage_Module function, can you help me understand what I'm wrong?
Code example.php
function getFunctionModule() {
require "module.php";
$func = "Usage_Module";
if (!function_exists($func)) {
echo "function not found";
}
return (array) $func();
}
$data = ['status' => 'ok'];
$data = array_merge(getFunctionModule(), $data);
print_r($data);
Code module.php
function Usage_Module()
{
$data = ['licensekey2' => 'ok'];
return (array) $data;
}
I have a database table named 'services'. With the function below I get all the records from that table. This function is located in my ServicesController.php.
public function index() {
$roadmap = Roadmap::all();
return view('services', compact('roadmap'));
}
Now in my view I also do the following:
<?php
foreach($roadmap as $roadmap_item) {
$new = array();
$splitted = explode("|", $roadmap_item->steps);
foreach($splitted as $split) {
$new = explode(":", $split);
}
}
?>
Lets say I get the string 'step1:hello|step2:bye' back from '$roadmap-item->steps'. I split them in substrings with explode etc. This is working by the way.
But is there a way I can manipulate the string in the Controller so my view will be nice and clean without many php code and still remain the variable $roadmap with all the database records.
Kind regards,

I think you can do very similar things in your controller. Do foreach in your controller first then make a changes in every item in your collection and pass the new collection.
For example:
$roadmaps = Roadmap::all();
foreach($roadmaps as $roadmap){
$roadmap->something = " the changes you want to do as string " . $roadmap->something;
$roadmap->save();
}
return view('services', compact('roadmaps'));
or
$roadmaps = Roadmap::all();
$new = new Collection();
foreach($roadmaps as $roadmap){
$new[] = array('roadmap' => $roadmap, 'something' => $roadmap->string . " etcetc ")
$new->save();
}
return view('services', compact('new'));
I was coding a TemplateView Class which is replacing #somevariable# placeholders with it's controller set correspondent. ViewHelpers are called via placeholders that simulate a function like #headerFiles()# for example.
The thing missing is a foreach loop definition like for example the smarty
{foreach from=$var key=index item=value} definition.
Until now I was iterating over a database object inside the controller and having a heredok or string concatenation assigned to the view. So there is a lot of html inside the controllers which I think should not be the controllers job.
I already implemented smarty into the app for testing and it's working fine - But when I decide to really use it I would have to change so many things like all partial templates would have to be .tpl files and all template directories would have to be merged ? or in one place and so on.
So my question is:
Are there any good examples or codesnippets I could use to implement a custom foreach loop method ? Before I have to change everything to use smarty. I also want to avoid using plain php like <?php foreach(): endforeach; ?>
UPDATE:
what concerns would one have going this direction ?
In a template:
#foreach array#
if($key !== 'fart'){
echo $val;
}
#endforeach#
class Foreacher {
private $template;
protected $array = array('fart' => 'poop', 'foo', 'bar');
public function __construct($template){
$this->template = file_get_contents($template);
}
public function parse(){
if(preg_match_all('/#foreach ([\w]+)#(.*?)#endforeach#/is', $this->template, $matches, PREG_SET_ORDER)){
$var = $matches[0][1];
$freach = "<?php foreach(\$this->$var as \$key => \$val){";
$freach .= $matches[0][2];
$freach .= "} ?>";
$parsed = str_replace($matches[0][0], $freach, $this->template);
$this->render($parsed);
}
}
public function __get($var){
if(isset($this->$var)){
return $this->$var;
}
return null;
}
protected function render($string){
$tmp = tmpfile();
fwrite($tmp, $string);
fseek($tmp, 0);
ob_start();
$file = stream_get_meta_data($tmp);
include $file['uri'];
$data = ob_get_clean();
fclose($tmp);
echo $data;
}
}
I'm scanning a folder and it's subfolders for files with PHP. I want to store the folders and files in a PHP array so I can create a treeview in another page. This is the format I get files paths in:
/home/project/index.php
/home/project/folder/myclass.php
/home/project/folder/myclass2.php
/home/project/folder/subfolder/anotherclass.php
I want to get these files in the following array:
[home][project] = array('index.php')
[home][project][folder] = array(myclass.php, myclass2.php)
[home][project][folder][subfolder] = array(anotherclass.php)
Note that the folder structure can change at any point. How can I achieve this?
The easiest way would be to use the built in (SPL) DirectoryIterator class and a simple recursive function.
An untested example:
public function directoryToArray($directoryPath)
{
$items = new DirectoryIterator($directoryPath);
$data = array();
foreach($items as $item) {
$name = $item->getFileName();
if ($item->isFile()) {
$data[] = $name;
}
else if ($item->isDir()) {
$data[$name] = directoryToArray($item->getPath());
}
}
return $data;
}
I have a static method 'findAll' on a model which basically gets all rows with certain criteria. This method works fine and I can call it using:
$m::findAll();
Where $m is the model name as a variable. I can output this and it returns correct results. However, when assigning this to a variable in the Zend_View object, as:
$this->view->viewvariable = $m::findAll();
I get the error:
Zend_Db_Table_Exception: Too many
columns for the primary key
Any ideas why?
Find all function:
final public static function findAll($where = false, array $options = array()) {
$object = new static();
if (!empty($options)) $options = array_merge($object->options, $options);
else $options = $object->options;
$run = $object->buildDefaultSelect($where, $options);
$rows = $run->fetchAll();
if ($options['asObject'] == true) {
$result = array();
foreach ($rows as $r) {
$class = new static();
$class->setInfo($r);
$result[] = $class;
}
return $result;
} else {
if (count($rows) > 0) return $rows;
else return array();
}
}
Note: This function works fine everywhere apart from when assigning to a view variable. If I run the below (not assigning it to a view variable), it shows the correct array data.
var_dump($m::findAll($module['where'], $module['options']));
exit;
In my view (I have replaced the actual name with viewvariable for the sake of this post):
<?php foreach($this->viewvariable as $item) { ?>
//Do some echoing of data in $item
//Close foreach
I doubt the issue is with Zend_View. It's hard to tell without seeing your code, but my guess is that findAll() is using the Zend_Table_Db find() function incorrectly.
To my knowledge, the only place that throws that exception is the find() function on Zend_Db_Table_Abstract.
Perhaps, inside the findAll() function (or in a function it calls) you're doing one of these:
$zendDbTable->find(1,2) //is looking for a compound key
$zendDbTable->find(array(1,2)) //is looking for two rows
When you really want the opposite.
