If enabled, allow_url_fopen allows PHP’s file functions to retrieve data from remote locations such as an FTP server or web site, and could lead to code injection vulnerabilities.

You can enable ‘allow_url_fopen’ by editing your php.ini file.

Find the php.ini file with this path:  /home/00000/etc/php.ini.   (where 00000 will be your Site Number).

Search or Add  this “allow_url_fopen”  and change the value with On.

allow_url_fopen = On

Also be sure to add the following to your php.ini:

memory_limit = 100M

cgi.fix_pathinfo=1

The problem

I have some 5-10 radio options (only one is selectable). i select and save the value.
now when showing the form again how do i select the previously selected radio again?

Common solution

compare the saved value 5-10 times with the values of radio options and echo checked=”checked” where matched

Uncommon solution [did it myself ]

eg/

<code>

<input name=”backup_what” type=”radio” value=”full” /> Full backup (wp-content folder and Database)

<input name=”backup_what” type=”radio” value=”db” /> Only Database

<input name=”backup_what” type=”radio” value=”content” /> Only wp-content folder

</code>

get the selected value in a variable say $radio_val
now to use php’s versatility

$$radio_val = ‘checked=”checked”‘;

notice the double $… what it does is it will make a new variable like $full or $db or $content depending on the value saved

then just echo respective values in the radio options

<input name=”backup_what” type=”radio” value=”full”  <?php echo $full; ?> /> Full backup (wp-content folder and Database)

<input name=”backup_what” type=”radio” value=”db” <?php echo $db; ?> /> Only Database

<input name=”backup_what” type=”radio” value=”content” <?php echo $content; ?> /> Only wp-content folder

Please use and try to find more uses of this if possible…
