I am having some issue with sql... Below have a working and not working example. I hard coded them so its easier to see.
$deleteData = $con->prepare("DELETE FROM markers WHERE sid=? AND user_id=? AND lat=? AND lng=?");
$deleteData->bind_param("iidd", $sid, $user_id,$lat,$lng);
$sid= '239';
$user_id = '2';
$lat = '39.724869';
$lng = '-91.400116';
$deleteData -> execute();
Some reason when I attempt to delete using type double in bind_param just doesn't work. Any suggestions? I changed it with or without '' around the lat lng, still doesn't work.
If I change it to below, it deletes just fine.
$deleteData = $con->prepare("DELETE FROM markers WHERE sid=? AND user_id=?);
$deleteData->bind_param("ii", $sid, $user_id);
$sid= '239';
$user_id = '2';
$deleteData -> execute();
First of all you have a syntax error in the second example (missing character ").
Also you did not assigned $sid variable.
Then I have a little bit stupid question. Are you aware, that assign of variables $blog_id, $user_id ... etc. must be before call of method $deleteData->bind_param()?
And also, don't forget that when you are comparing 2 real values, then you should also add some tolerance, so try instead:
$deleteData = $con->prepare("DELETE FROM markers WHERE sid=? AND user_id=? AND ABS(lat - ?) < 0.0000001 AND ABS(lng - ?) < 0.0000001");
Replace $blog_id = '239';with $sid = '239'; since that's the variable name you use in the bind_param() statement.

I have an SQR code like this:
begin-procedure SPL-REMOVE($Vndr_Name_Shrt_Usr, :$outputshrt)
Let $valid_chars_shrt = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz -.:/'#0123456789#()=+%*"£$'
Let $invalid_chars_shrt = translate($Vndr_Name_Shrt_Usr, $valid_chars_shrt, '')
Let #invalid_shrt = length($invalid_chars_shrt)
If #invalid_shrt
Let $outputshrt = translate($Vndr_Name_Shrt_Usr, $invalid_chars_shrt, '')
Else
Let $outputshrt = $Vndr_Name_Shrt_Usr
End-if
end-procedure
And upon running the SQR, I am getting this error:
(SQR 4008) Unknown function or variable in expression: #0123456789#
Let $valid_chars_shrt = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz -.:/'#0123456789#()=+%*"£$'
May I know why is that so? How can I avoid such error from coming up?
If this is truly the code:
Let $valid_chars_shrt = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz -.:/'#0123456789#()=+%*"£$'
The problem lies with the single quote before the #012345678. It unbalances the quoted string. Change it to TWO single quotes '' (not a double-quote). That should work but unless I test it, no guarantees.
I have been looking for a solution everywhere on the internet but nowhere I can see a single script which lets me read the name of a variable as a string in Godot 3.1
What I want to do:
Save path names as variables.
Compare the name of the path variable as a string to the value of another string and print the path value.
Eg -
var Apple = "mypath/folder/apple.png"
var myArray = ["Apple", "Pear"]
Function that compares the Variable name as String to the String -
if (myArray[myposition] == **the required function that outputs variable name as String**(Apple) :
print (Apple) #this prints out the path.
Thanks in advance!
I think your approach here might be a little oversimplified for what you're trying to accomplish. It basically seems to work out to if (array[apple]) == apple then apple, which doesn't really solve a programmatic problem. More complexity seems required.
First, you might have a function to return all of your icon names, something like this.
func get_avatar_names():
var avatar_names = []
var folder_path = "res://my/path"
var avatar_dir = Directory.new()
avatar_dir.open(folder_path)
avatar_dir.list_dir_begin(true, true)
while true:
var avatar_file = avatar_dir.get_next()
if avatar_file == "":
break
else:
var avatar_name = avatar_file.trim_suffix(".png")
avatar_names.append(avatar_name)
return avatar_names
Then something like this back in the main function, where you have your list of names you care about at the moment, and for each name, check the list of avatar names, and if you have a match, reconstruct the path and do other work:
var some_names = ["Jim","Apple","Sally"]
var avatar_names = get_avatar_names()
for name in some_names:
if avatar_names.has(name):
var img_path = "res://my/path/" + name + ".png"
# load images, additional work, etc...
That's the approach I would take here, hope this makes sense and helps.
I think the current answer is best for the approach you desire, but the performance is pretty bad with string comparisons.
I would suggest adding an enumeration for efficient comparisons. unfortunately Godot does enums differently then this, it seems like your position is an int so we can define a dictionary like this to search for the index and print it out with the int value.
var fruits = {0:"Apple",1:"Pear"}
func myfunc():
var myposition = 0
if fruits.has(myposition):
print(fruits[myposition])
output: Apple
If your position was string based then an enum could be used with slightly less typing and different considerations.

Can't you just use the str() function to convert any data type to stirng?
var = str(var)
I need a wordpress loop that for every post checks a meta numeric variable previously assigned to each of the taxonomies of the post and returns the sum of these meta variables.
To do so, I think I need a dynamic variable name for the total. I mean something like:
variablerelatedtopost = metataxonomy1 + metataxonomy2 + ... + metataxonomyn
echo variablerelatedtopost
How can I do that? Is it possible to generate a dynamic numeric variable via loop? and HOW can I refer to it in a general way, without adressing it with its name?
Thanks everyone! And sorry for possible English mistakes :P
EDIT: I just realized the code by Alex is not what I wanted. I need a variable which changes name at every post and which value is always = 0. Is there a solution?
can you not just add a counter to your loop like this?
//Total should start # 0 before the loop
$total = 0;
// The Query
$the_query = new WP_Query($args);
// The Loop
while ( $the_query->have_posts() ) : $the_query->the_post();
$amount = get_post_meta($post->ID, 'the_meta_data_field', true);
$total = $total + $amount;
endwhile;
//echo total
echo $total;
I found the solution to my problem: an array which increases its lenght at every cicle of the loop. I know it's simple but since I'm just a beginner it took me a while to think about it. I post the code here so maybe it can help someone (and if you find bugs or have improvements, please tell me)
//Before the loop, empty array
$totale = array();
// WP Loop
while ( $loop->have_posts() ) : $loop->the_post();
$totale[] = 0;
$indice = (count($totale)) - 1;
// $termvariable was previously set up as a term meta value
if( has_term( 'numberofterm', 'nameoftaxonomy' ) ) {
$totale[$indice] = $termvariable + $totale[$indice];
}
Here is my code
if(!$criteria){
return null;
}
$em = $this->doctrine->getEntityManagerForClass('Sample\MyBundle\Entity\Call');
$qb = $em->createQueryBuilder();
$qb->add('select', 'c')->add('from', 'Sample\MyBundle\Entity\Call c');
if($criteria->getReason() && $criteria->getReason() != null){
$qb->add('where', 'c.reason = ?1');
$qb->setParameter(1, $criteria->getReason());
}
if($criteria->getCallDate() && $criteria->getCallDate() != null){
$qb->add('where', 'c.callTime = ?2');
$qb->setParameter(2, $criteria->getCallDate());
}
if($criteria->getPage()>1){
$qb->setFirstResult(($criteria->getPage()-1) * 10)->setMaxResults(10);
}
$query = $qb->getQuery();
return $query->getResult();
I'm getting this error - Invalid parameter number: number of bound variables does not match number of tokens I googled but couldn't found a solution. Need help with this.
I even tried to put both setParameter() calls after conditional check if statements but that also give the same error. If I don't set the second parameter and remove second where condition then it works.
Oh, I guess I was making a mistake. I think I can not use multiple 'where' in 'add' function. I replaced it with $qb->andWhere('c.callTime > ?2'); and now it works fine.
I've noticed that when ordering by a datetime column in CI with active record, it's treating the column as a string, or int.
Example:
$this->db->limit(12);
$this->db->where('subscribed',1);
$this->db->join('profiles','profiles.user_id=users.id');
$this->db->where('active',1);
$this->db->select('users.thumbUpload,users.vanity_url');
$this->db->select('users.created_on as time');
$this->db->order_by('time');
$query = $this->db->get('users');
This is where users.created_on is a datetime field. Firstly, is it because active record is rendering time escaped, or is it something else? And if it is, can I prevent the escaping on order_by somehow?
Also, stackoverflow, please stop autocorrecting 'datetime' to 'date time'. It's annoying.
Cheers!
When you set second argument as false, function wont check and escape string. Try this
$this->db->select('users.created_on as time', FALSE);
Or for you query use
$this->db->order_by('users.created_on', 'DESC'); //or ASC
And for complex queries
$this->db->query("query");
According to the signature of the method in core files of CI (currently 2.2), it does not have any option to allow to choose whether or not to escape.
// The original prototype of the order_by()
public function order_by($orderby, $direction = '') {
// Definition
}
As you see there is not argument as $escape = true in the argument list. One way to do so is to hack this core file (I normally do not suggest it, since if you upgrade CI to a newer version later, then these changes will be lost, but if you do not intend to do so, it is OK to use it).
To do so, first change the prototype as:
public function order_by($orderby, $direction = '', $escape = true) {
// Definition
}
And then check the conditions in the following parts of definition:
// Line 842
if($escape){
$part = $this->_protect_identifiers(trim($part));
}else {
$part = trim($part);
}
// Line 856
if($escape){
$orderby = $this->_protect_identifiers($orderby);
}
When you call it, to prevent the escaping:
$this->db->order_by($ORDERBY_CLAUSE, null, false);
