I filter job offers on data from a database. As long as the table contained up to 10,000 records, everything worked great.
$searchQuery = \App\JobOffers::searchOffer($search_text, $search_location, $job_function, $job_type, $job_experience, $date_filter, $last);
Now the table has over 60,000 records with job offers. When I wants to perform filtering, the application returns error 500.
I can't find a solution to this problem.
I thought about using 'chunk'. I don't know if this solution will help.
foreach ($all->chunk(100) as $key => $chunk) {
$chunk = $chunk->all();
$test = $chunk::searchOffer($search_text, $search_location, $job_function, $job_type, $job_experience, $date_filter, $last);
$searchQuery->push($test);
}
In the above example I get an error: "Class name must be a valid object or a string".
Is there any way to solve this problem?

I think I've worked out that the issue relates to binding params for PDO instead of including the values in the select statement.
Now googling how to bind array values where there will be a variable number of them per query type. For example there may be one, two or three category (col) values sought.
My primary script submits an ajax request to a secondary script.
Two params are sent and are being received in most scenarios.
eg department:mens-fashion, category:coats-and-jackets
In all but a few scenarios, the ajax query is successful and returns as expected. However, for some pairings of params, nothing is displayed in the page or in console.
Having returned from the query script immediately after building the query, I know the query is always working OK. (Copying and pasting into phpMyAmdin brings me the correct resultset.)
So it seems the key part of the script is the fetch routine. How can I catch an error message from PDO in the next line?...
$filtered_results = $filtered_statement->fetchAll(PDO::FETCH_ASSOC);
$debugInfo = array('debug' => vsprintf(str_replace("?", "%s", $filtered_statement->queryString), $opts ));
[edit]
if ( is_array($filtered_results) ) {
$filtered_results = array_merge($debugInfo, $filtered_results);
} else {
$filtered_results = $debugInfo;
}
[/edit]
debug info still only being returned if the query was a success.
$filtered_results_json = json_encode($filtered_results);
echo( $filtered_results_json );
Please would anyone point me to a solution where, the failed query will display in the calling script. The data required is in the db so I am still really stuck on trying to display failure messages.
You need to check whether an array is returned or not. If nothing was found no array is being returned - and you can't use array_merge.
$filtered_results = $filtered_statement->fetchAll(PDO::FETCH_ASSOC);
$debugInfo = array('debug' => vsprintf(str_replace("?", "%s", $filtered_statement->queryString), $opts ));
if ( is_array($filtered_results) ) {
$filtered_results = array_merge($debugInfo, $filtered_results);
} else {
$filtered_results = $debugInfo;
}
$filtered_results_json = json_encode($filtered_results);
echo( $filtered_results_json );

I'm working on a project with laravel and I have to ask to database some queries that have to return an array. This is the code that I have
Logged as a teacher:
$teacher= Teacher_Admin::where('id_user', Auth::user()->id)->first();
$grades = Grade::where('id_depar', $teacher->id_depar)->get(); //3 grades
$studients_grades = Studient_Grades::where('id_grade', $grades->id)->get(); //5 studient
$studients = Studient::where('id', $studients_grades->id_studient)->get(); //5 studient
$user = User::where('range', 2)->get();//5 users
What I'm trying to do is look for all the studients that are enrolled on a grade that is on the department of the teacher, e.g. Departments: IT, Chemistry. In IT department we have two Grades: Frontent Development and Backend Development. And I have 30 studient per grade. How I can get the 60 studients?
If you need more code please ask, this is my first question and I'm not sure how to do this
Thanks in advice
Finally I got it. When I start receiving get() answers, it returns a multiple array so I have to parse to something like this
$teacher= Teacher_Admin::where('id_user', Auth::user()->id)->first();
$grades = Grade::where('id_depar', $teacher->id_depar)->get();
$id_grades = []
foreach ($grades as $grade){
$id_grades = $grade->id
}
$studients_grades = Studient_Grades::whereIn('id_grade', $id_grades)->get();
I was able to work with this :) Hope to help someone someday
I'm brand new to phpunit and attempting to write a test that asserts that three notes were created, but I'm getting all of the notes from the DB.
/** #test */
public function it_gets_notes()
{
$address = Address::first();
$notes = factory(AddressNote::class, 3)->create(['address_id'
=> $address->id]);
$found = $this->notesClass->getData(['address_id' => $address-
>id]);
$this->assertCount(3, $found);
}
}
The Address and AddressNote models are working properly. I think I'm most confused about the getData method, which I know I need for my code coverage. Anyone see what I'm missing that would generate the error in the title?
If you need to check the difference after running your create method, then save $found before and after adding them, and the subtraction will be your number:
public function it_gets_notes()
{
$address = Address::first();
$found = $this->notesClass->getData(['address_id' => $address->id]);
$notes = factory(AddressNote::class, 3)->create(['address_id' => $address->id]);
$foundAfter = $this->notesClass->getData(['address_id' => $address->id]);
$difference = count($foundAfter) - count($found);
$this->assertEquals(3, $difference);
}
Note that you need to use assertEquals() with 3 and the difference now instead of assertCount(), since you're comparing numbers.
I don't know the whole your story, but I assume that your first mistake was that you did not create a testing database.
So, that would be the first step - in addition to your databaseName (whatever the name) create a databaseName_test.
There are some other steps to do - in your ,env file change the name of the databaseName to databaseName_testing - but only while you're doing your testing (and then immediately rollback to your original databaseName).
Yet, the problem can still persist (PHP Unit is not a perfect tool, just like PHP), and here is the hack that can help.
Instead of:
$this->assertEquals(3, $difference);
write:
$this->assertEquals(11935, $difference); //the number is specific for your case
Yep, it's stupid, but it should work...
Using a mysqli prepared statement I would like to insert an array into a mysql database table.
Being aware that bind-param and arrays do not go together, we would like to write the query in php first, then process this as a prepared statement:
$tagQuery = "INSERT INTO word_tags(speaks) VALUES ";
// Count total array values
$icoderayInsideCount = count($icoderayInside);
foreach ($icoderayInside as $icoderayInsideKey=>$icoderayInsideValue)
{
// Last value
// Currrent Array Key Total / Last Array Value
if ($icoderayInsideKey == $icoderayInsideCount)
{
$tagQuery .= "('$icoderayInsideValue')";
}
// All other values
else
{
$tagQuery .= "('$icoderayInsideValue'), ";
}
}
// Send array (keywords) to database
if ($stmt2 = $link2->prepare($tagQuery))
{
if (!$stmt2->execute())
{
// #2 If it can prepare but can't execute, why?
echo "Error {$link2->errno} : {$link2->error} (Cant execute?) <br/>";
// Dump query to check the end result
var_dump($tagQuery);
exit();
}
$stmt2->close();
}
else
{
// #1 If it cant prepare, why?
echo "Error {$link2->errno} : {$link2->error} (Cant prepare?)";
exit();
}
When i run this via PHP / Server i get:
Error 1064 : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('DONGLES'),' at line 1 (Cant prepare?)
So, the statement prepares but is not being executed.
The value of the generated query, $tagQuery is:
INSERT INTO word_tags(speaks) VALUES ('PMP3670B_BK'), ('PRESTIGIO'), ('MULTIPAD'), ('7"'), ('800X480'), ('1GHZ'), ('ARM'), ('CORTEX'), ('A8'), ('CPU'), ('512MB'), ('DDR3'), ('DRAM'), ('ANDROID'), ('4.1'), ('JELLY'), ('BEAN'), ('MALI'), ('400'), ('MP'), ('GPU'), ('VIDEO'), ('4GB'), ('INTERNAL'), ('FLASH'), ('MEMORY'), ('SUPPORT'), ('32GB'), ('SDHC/SD'), ('USB/WI-FI/HEADSET'), ('PORT'), ('LITHIUM'), ('POLYMER'), ('BLACK'), ('HDMI'), ('OUTPUT'), ('UPTO'), ('1080'), ('HD'), ('USB2.0'), ('MINI'), ('HIGH'), ('SPEED'), ('FOR'), ('3G'), ('DONGLE'), ('OTG'), ('CABLE'), ('INCLUDED')
The fourth value from the end is('DONGLE') which is what the error message is complaining about.
When i run this exact same query through phpmyadmin there is no error involved.
What i assume is happening, is that there is some kind of length limit involved within creating a prepared statement... Or something to this effect.
Have scratched my brains for hours now to try to solve this and have not found any relating information.
If anyone could offer some assistance / advice / indication / input or otherwise as to what the conflict of problem may be within this, it would be GREATLY appreciated.
Thanks so much for the time and effort in readying through this!
EDIT:
#Mihai - Thanks for the thought.
It seems that the word dongle does have something string to it. In the original string, before being parsed to an array, it looks like this: DONGLE,
I run preg_replace to remove this comma from the string before parsing it to an array:
$icode = preg_replace('#,#', '', $icode);
Then into an array:
$icoderayInside = explode(" ", $icode);
Still cannot think of any reason this would cause a conflict as the output string, the query is as i have previously stated and includes no comma, or anything... Any would be greatly appreciated!
EDIT 2:
#ShadyAtef
Original input is stored in mysql as varchar, latin_general_ci:
PRESTIGIO MULTIPAD, 7" 800X480, 1GHZ ARM CORTEX A8 CPU, 512MB DDR3 DRAM, ANDROID 4.1 JELLY BEAN, MALI 400 MP GPU, VIDEO, 4GB INTERNAL FLASH MEMORY, SUPPORT 32GB SDHC/SD, USB/WI-FI/HEADSET PORT, LITHIUM POLYMER, BLACK, HDMI OUTPUT UPTO 1080 HD, USB2.0 MINI HIGH SPEED PORT FOR 3G DONGLE, OTG CABLE INCLUDED
Brought into php then processed to an array with additional requirements:
// Convert Var a + b to String
$icode = $itemCode . ' ' . $description;
// Clean of Unwanteds
$icode = preg_replace('#,#', '', $icode);
$icode = preg_replace('#\(#', '', $icode);
$icode = preg_replace('#\)#', '', $icode);
// Creates array from sting
$icoderayInside = explode(" ", $icode);
// Remove array duplicates
$icoderayInside = array_unique($icoderayInside);
Before being built into the query. Any assistance would be GREATLY appreciated!
EDIT 3:
#ShadyAtef
// Currrent Array Key Total / Last Array Value
if ($icoderayInsideKey == $icoderayInsideCount)
{
// dump here shows:
$icoderayInsideKey == 49
$icoderayInsideCount == 49
}
This was really tricky,but I got it : The tricky wrong part is that
if ($icoderayInsideKey == $icoderayInsideCount)
It should be
if ($icoderayInsideKey == ($icoderayInsideCount-1))
Because the last key in the array equals to the array (length -1) So you should change your if condition
I am working on project where I need to implement SphinxSearch with Cake php. So I am simply trying to use a component and behaviour into it. The link to it, is :-
http://bakery.cakephp.org/articles/eugenioclrc/2010/07/10/sphinx-component-and-behavior
I am requesting Sphinx API like below :
$sphinx = array('matchMode' => SPH_MATCH_ALL, 'sortMode' => array(SPH_SORT_EXTENDED => '#relevance DESC'));
$results = $this->ModelName->find('all', array('search' => 'Search_Query', 'sphinx' => $sphinx));
pr($result);
For above it is working fine ,but when I tried to minimise the response time querying to a particular field of the table (using extended match modes,i.e. SPH_MATCH_EXTENDED2) , Sphinx just fails to output any result. The extended query which I used is given below :-
$sphinx = array('matchMode' => SPH_MATCH_EXTENDED2, 'sortMode' => array(SPH_SORT_EXTENDED => '#relevance DESC'));
$results = $this->ModelName->find('all', array('search' => '#Field_name Search_Query', 'sphinx' => $sphinx));
pr($results);
Can anyone recognise where am I going wrong with it? Please help if I am going wrong some where.
Thanks in advance.
Btw, when you use EXTENDED2 mode make sure your rank mode is set accordingly.
Edit:
Anyway back to you problem, looking at that component/behavior code you can see right away that no error checking is done whatsoever. Try changing the code a bit so you can at least see the errors and/or warnings.
Component
if(!isset($query['search'])){
$result = self::$sphinx->Query('', $indexes);
} else {
$result = self::$sphinx->Query($query['search'], $indexes);
}
if ($result === false) {
// throw new SphinxException();
die(self::$sphinx->GetLastError());
}
$warn = self::$sphinx->GetLastWarning();
if ($warn) echo $warn;
Behavior
$result=$this->runtime[$model->alias]['sphinx']->search($s);
if ($result === false) {
die($this->runtime[$model->alias]['sphinx']->GetLastError());
}
$warn = $this->runtime[$model->alias]['sphinx']->GetLastWarning();
if ($warn) echo $warn;
I hope that helps.
As you said ,
Sphinx just fails to output any result.
That means it's an error :
Please check whether you have added the specific field to the indexing by using sql_query
Also check if the field you are searching for is not an attribute
As per the sphinx documentation :
Attributes, unlike the fields, are not full-text indexed. They are stored in the index, but it is not possible to search them as full-text, and attempting to do so results in an error.
