This is my search code please see then solution, thank you.
You have to use like this
$report_ex = Expenses::where(condition)->where(condition)->get();
or
$report_ex = Expenses::where(condition)->where(condition)->first();
If you are using
$report_ex = Expenses::where(condition)->where(condition)->first();
then you need to call
if(!empty($report_ex))
{
// your code
}
else
{
//your code
}
But if you are using
$report_ex = Expenses::where(condition)->where(condition)->get();
then you should use
if(count($report_ex) > 0)
{
// your code
}
else
{
// your code
}
since get function returns an empty object
I am trying to open different views based upon a request value. For example, if the value of $request is set to one, then view one should open. If the $request value is two, then view two should open.
My code is working fine, but right now, I will have to repeat code for each view. How can I do it without repeating the if condition?
Scenario
public function printreports(Request $request)
{
$reports = $request->get('reports');
if ($reports === 1) {
return view('teachers.report1', compact('anything'));
}
if ($reports === 2) {
return view('teachers.report2', compact('anything'));
}
}
For large amount of files with similar name pattern:
$viewName = sprintf('teachers.report%d', $request->get('reports', 1))
if (!\View::exists($viewName)) {
___ throw an error or return default view ____
}
return view($viewName, compact('anything'));
I'm using chunk() to find a value from the database based on the question. But how do I return the entityFound[] array?
$chunkRecord = $this->company()->entityValues()->chunk(5,
function ($entityValues) use ($entityFound, $question) {
foreach ($entityValues as $entityValue)
if (str_contains($question, $entityValue->name))
$entityFound[] = $entityValue->name;
return $entityFound;
});
// I want to run this array and do something else.
dd($entityFound);
I have the following database design
I have several different Documents I want a user to be able to create. Each document has its own view for the creation of the document, or the editing.
If the document they are trying to create has already been created, they should see the edit page for that document.
At the moment, I have the following
public function create(Project $project)
{
$documentTypesCreated =
$project->document()
->join('document_type', 'documents.id', '=', 'document_type.documentId')
->select('document_type.documentId', 'document_type.name')
->get();
$documentLink = $_GET['documentType'];
if($documentTypesCreated->isEmpty()){
return View::make($documentLink.'Doc.create', compact('project'));
} else {
foreach($documentTypesCreated as $documentName) {
if($documentName->name != $documentLink) {
return View::make($documentLink.'Doc.create', compact('project'));
} else {
$document = Document::find($documentName->documentId);
return View::make($documentLink.'Doc.edit', compact('project', 'document'));
}
}
}
}
Breaking this up, I am doing the following:
Firstly, I get all the Documents that have been created for a Project
$documentTypesCreated =
$project->document()
->join('document_type', 'documents.id', '=', 'document_type.documentId')
->select('document_type.documentId', 'document_type.name')
->get();
I then get the Document the user is trying to create from the URL
$documentLink = $_GET['documentType'];
So lets say that the query returns that this Project has
DocumentA
DocumentB
And the documentLink shows that I am trying to create DocumentB.
Because DocumentB has already been created, I need the edit page for this Document. Firstly, I check if the query returned and Documents
if($documentTypesCreated->isEmpty()){
return View::make($documentLink.'Doc.create', compact('project'));
} else {
}
If it didnt, it will show the create page for the chosen Document. If it did, the else statement will kick in.
Within the else statement, I loop through all the Documents the query returned
foreach($documentTypesCreated as $documentName) {
}
I then do the following, and this is where my logic is failing
if($documentName->name != $documentLink) {
return View::make($documentLink.'Doc.create', compact('project'));
} else {
$document = Document::find($documentName->documentId);
return View::make($documentLink.'Doc.edit', compact('project', 'document'));
}
If the document Name from the query is not equal to the document I am trying to create, then I show the create page for that Document. Otherwise, I show the edit page.
Now lets get back to where I chose DocumentB. I know that I have already created this Document, so I should see its edit page. However, because DocumentA is the first result returned in the query, the above statement looks like the following
if("DocumentA" != "DocumentB") {
return View::make($documentLink.'Doc.create', compact('project'));
} else {
$document = Document::find($documentName->documentId);
return View::make($documentLink.'Doc.edit', compact('project', 'document'));
}
So it is going to show the create page for DocumentB, not the edit page. If DocumentB was the first result returned, then the edit page would be displayed.
I Hope this makes sense. How can I get it displaying the correct view for the document?
Thanks
Controller
Base on your query - you may set these variables manually
$create = true;
$edit = false;
Logic
if ($query == 'any logic') {
$create = true;
$edit = false;
}else{
$create = false;
$edit = edit;
}
Then, send them over to your view.
View
#if($create == true)
//.. Show Create Form
#else
// .. Show Edit Form
#stop
Then, your view will render base the result of your query. I hope this help !
While editting a product in the backend I need to know whether any of it's data has been changed or not?
$product->hasDataChanges() always return true even I didn't modify any fields.
Why does $product->hasDataChanges() always return true even I didn't modify any fields.?
Looking into the Varien_Object function setData function it appears that hasDataChanges is always set to true even if technically the data has not changes.
public function setData($key, $value=null)
{
$this->_hasDataChanges = true;
if(is_array($key)) {
$this->_data = $key;
$this->_addFullNames();
} else {
$this->_data[$key] = $value;
if (isset($this->_syncFieldsMap[$key])) {
$fullFieldName = $this->_syncFieldsMap[$key];
$this->_data[$fullFieldName] = $value;
}
}
return $this;
}
Solution:
When you have a model which is an type of Mage_Core_Model_Abstract, then you can easily get the previous data (original data) on save using public function getOrigData($key=null) method.
getOrigData() returns the data in the object at the time it was initialized/populated.
After the model is initialised you can update that data and getData() will return what you currently have in that object.
Have a look at Varien_Object (getOrigData,setOrigData) so you can have a look at how and why it is used.
