When you are creating a page where the file is uploaded in the form and these files are saved on your server. Sometimes it happens that same name files overwrites the files. To avoid this just add the below line of code.
$config['encrypt_name'] = TRUE;
Here is the block of code which will give the full url of the page:
$page_url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
When we add ckeditor textarea, it shows default text in the textarea – ‘This is my textarea to be replaced with CKEditor’.
To remove this default text from textarea, just use the below code :
CKEDITOR.instances.TEXTAREAID.setData('');
var value = 1,2,3,4,5;
var remove_val = '3';
var separator = ",";
var new_value = value.split(separator);
for(var i = 0 ; i < new_value.length ; i++) {
if(new_value[i] == remove_val) {
new_value.splice(i, 1);
return new_value.join(separator);
}
}
Usually we use foreach loop when there is a need to use only one array. But what if there are more than one array…
Foreach loop works only with a single array. To step through multiple arrays it’s better to use the each() function in a while loop. Have a look at it..
while(($code = each($codes)) && ($name = each($names))) {
echo '<option value="' . $code['value'] . '">' . $name['value'] . '</option>';
}
each() returns information about the current key and value of the array and increments the internal pointer by one, or returns false if it has reached the end of the array. This code would not be dependent upon the two arrays having identical keys or having the same sort of elements. The loop terminates when one of the two arrays is finished.
To get the data between two dates in CodeIgniter, you can use the BETWEEN Operator. The BETWEEN operator selects values within a given range. The values can be numbers, text, or dates. More
$this->db->query("SELECT * FROM TABLE WHERE date BETWEEN '$startDate' AND '$endDate'");
When you want to compare values in PHP then you can use either == or === operator. But these both operator are not same. It’s good to know the difference between them.
These both operators fall under the category of Comparison Operators. The first operator ‘==’ is known as Equal Operator in PHP and checks for the equal values and the second operator ‘===’ is known as Identical Operator and checks for equal values and it also checks that if both the values are of same variable type or not.
Yes, you can remove the index.php from your url in your CodeIgniter web application.
You just need to add a .htaccess file in your web application folder.
Create a file and give it name .htaccess and save it in the root folder, and then copy the below block of code and paste it in the .htaccess file.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
One more change you have to do in your config.php file.
Go to :
application/config/config.php
and remove index.php from $config[‘index_page’]
All Done. Enjoy!
Sometimes while sending a SMS, we need to add a new line or a link break in our sms. There are many ways to add a line break. But now every method will work in your case because it depends on how you are sending your SMS.
I Method :
Add “\r\n” in your SMS.
II Method :
Add “%0a” in your SMS.
Note : Encode your message with ” ” (double quotes) not ‘ ‘ (single quotes).
If you have a PHP Array and want to perform some javascript operations by looping the PHP Array, then I recommend you to use PHP foreach loop instead of Javascript forEach loop.
function myfunction() {
<?php foreach($myArray as $val) { ?>
console.log('<?=$val;?>');
<?php } ?>
}
