Follow this example to create a variable outside functions, and use it inside the functions: MyVariable = 99 #this is a global variable def changeAndPrint_GlobalVariable(): global MyVariable #use global variable in this function with "global" keyword print('Global variable "MyVariable" before changeRead more

Follow this example to create a variable outside functions, and use it inside the functions:

MyVariable = 99 #this is a global variable

def changeAndPrint_GlobalVariable():
    global MyVariable  #use global variable in this function with "global" keyword
    print('Global variable "MyVariable" before change = ', MyVariable) # the global variable is printed
    MyVariable = 1  #change the value of the global variable is printed
    print('Global variable "MyVariable" after change = ', MyVariable) # the global variable is printed

def changeAndPrint_LocalVariable():
    MyVariable = 77 #this is a local variable
    print('Local variable "MyVariable" = ', MyVariable) #the local variable is printed

changeAndPrint_GlobalVariable() #call the function
changeAndPrint_LocalVariable() #call the function

MyVariable = 99 #this is a global variable

def changeAndPrint_GlobalVariable():

global MyVariable #use global variable in this function with "global" keyword

print('Global variable "MyVariable" before change = ', MyVariable) # the global variable is printed

MyVariable = 1 #change the value of the global variable is printed

print('Global variable "MyVariable" after change = ', MyVariable) # the global variable is printed

def changeAndPrint_LocalVariable():

MyVariable = 77 #this is a local variable

print('Local variable "MyVariable" = ', MyVariable) #the local variable is printed

changeAndPrint_GlobalVariable() #call the function

changeAndPrint_LocalVariable() #call the function

This code will print:

Global variable "MyVariable" before change =  99
Global variable "MyVariable" after change =  1
Local variable "MyVariable" =  77

Global variable "MyVariable" before change = 99

Global variable "MyVariable" after change = 1

Local variable "MyVariable" = 77

Hi, This is the syntax to concatenate strings: $text1 = "hello"; $text2 = "world"; $text = $text1 . ' ' . $text2; For your code, use this: function UppercaseText($text_list) { $GlobalText = ""; $TableSize = sizeof($text_list);; for ($i = 0; $i < $TableSize; $i++) { $BigText[] = strtoupper($text_lRead more

Hi,

This is the syntax to concatenate strings:

$text1 = "hello";
$text2 = "world";
$text = $text1 . ' ' . $text2;

$text1 = "hello";

$text2 = "world";

$text = $text1 . ' ' . $text2;

For your code, use this:

function UppercaseText($text_list) {
	$GlobalText = "";
	$TableSize = sizeof($text_list);;
  	for ($i = 0; $i < $TableSize; $i++) {
    $BigText[] = strtoupper($text_list[$i]);
    $GlobalText .=  strtoupper($text_list[$i]);
    if ($i != $TableSize-1) {
    $GlobalText .= " ";
    }
  }
  //return $BigText;
  return $GlobalText;
}
$text_list = ['the', 'train', 'was', 'late'];
var_dump(UppercaseText($text_list));

function UppercaseText($text_list) {

$GlobalText = "";

$TableSize = sizeof($text_list);;

for ($i = 0; $i < $TableSize; $i++) {

$BigText[] = strtoupper($text_list[$i]);

$GlobalText .= strtoupper($text_list[$i]);

if ($i != $TableSize-1) {

$GlobalText .= " ";

}

//return $BigText;

return $GlobalText;

}

$text_list = ['the', 'train', 'was', 'late'];

var_dump(UppercaseText($text_list));

Hi,

I think Yoast SEO removed metakeywords. Please see this aricle :

Meta keywords Why we don’t use them – and neither should you

use this key instead :

_yoast_wpseo_focuskw

You can update it like any post meta. This is the syntax:

//the value of the focus key word
$myFocusKeyword = "focus keyword example"; 
 //wrtie the value to postmeta key _yoast_wpseo_focuskw
$updatedKeyword = update_post_meta($post_id, ‘_yoast_wpseo_focuskw’, $myFocusKeyword);

//the value of the focus key word

$myFocusKeyword = "focus keyword example";

//wrtie the value to postmeta key _yoast_wpseo_focuskw

$updatedKeyword = update_post_meta($post_id, ‘_yoast_wpseo_focuskw’, $myFocusKeyword);

I tested it and it works fine.

In your error log I can see that the issue is with your %Q430.0 output.
Please check the network where your %Q430.0 output is writen. maybe the data (inputs and other data) used to calculate this output are changed in other tasks.

Hello,

You need to give access Outlook with VBA, you need to activate the Microsoft Outlook Object Library.

To activate it, go to Tools in the VBA editor > References.

Activate Microsoft Outlook 16.0 Object Library :

Then in a module use this subroutine:

Sub sendAnEmail(ByRef DomainName As String, ByRef SendTo As String, ByRef EmailSubject As String, ByRef EmailBody As String)

    'refer to outlook application
    Dim EmailApp As Outlook.Application
    Dim Source As String
    'launch outlook application
    Set EmailApp = New Outlook.Application
    'refer to a new outlook email
    Dim EmailItem As Outlook.MailItem
    'create a new outlook email
    Set EmailItem = EmailApp.CreateItem(olMailItem)
    
    EmailItem.To = SendTo 'the email adress who the email is sent to
    EmailItem.Subject = EmailSubject 'write your email subject in this variable
    EmailItem.HTMLBody = EmailBody
    Source = ThisWorkbook.FullName
    'send the new email
    EmailItem.Send
End Sub

Sub sendAnEmail(ByRef DomainName As String, ByRef SendTo As String, ByRef EmailSubject As String, ByRef EmailBody As String)

'refer to outlook application

Dim EmailApp As Outlook.Application

Dim Source As String

'launch outlook application

Set EmailApp = New Outlook.Application

'refer to a new outlook email

Dim EmailItem As Outlook.MailItem

'create a new outlook email

Set EmailItem = EmailApp.CreateItem(olMailItem)

EmailItem.To = SendTo 'the email adress who the email is sent to

EmailItem.Subject = EmailSubject 'write your email subject in this variable

EmailItem.HTMLBody = EmailBody

Source = ThisWorkbook.FullName

'send the new email

EmailItem.Send

End Sub

To test the code, call this code using a buton:

Sub testSendEmail()
    Dim SendTo, EmailSubject, EmailBody As String
    SendTo = "myemail@example.com"   ' put the email adress that will receive the email
    EmailSubject = "This is a send email test from Excel"  ' write your subject
    EmailBody = "This email is sent from Execl using Microsoft outlook library" ' put the body
    sendAnEmail DomainName, SendTo, EmailSubject, EmailBody  ' call the subroutine by passing the parameters
End Sub

Sub testSendEmail()

Dim SendTo, EmailSubject, EmailBody As String

SendTo = "myemail@example.com" ' put the email adress that will receive the email

EmailSubject = "This is a send email test from Excel" ' write your subject

EmailBody = "This email is sent from Execl using Microsoft outlook library" ' put the body

sendAnEmail DomainName, SendTo, EmailSubject, EmailBody ' call the subroutine by passing the parameters

End Sub

Test:

I hope this will help you.
