Question

I am writing a bash script in where I am trying to submit a post variable, however wget is treating it as multiple URLS I believe because it is not URLENCODED… here is my basic thought

MESSAGE='I am trying to post this information'
wget -O test.txt http://xxxxxxxxx.com/alert.php --post-data 'key=xxxx&message='$MESSAGE''

I am getting errors and the alert.php is not getting the post variable plus it pretty mush is saying

can’t resolve I
can’t resolve am
can’t resolve trying
.. and so on.

My example above is a simple kinda sudo example but I believe if I can url encode it, it would pass, I even tried php like:

MESSAGE='I am trying to post this information'
MESSAGE=$(php -r 'echo urlencode("'$MESSAGE'");')

but php errors out.. any ideas? How can i pass the variable in $MESSAGE without php executing it?

You want $MESSAGE to be in double-quotes, so the shell won’t split it into separate words, then pass it to PHP as an argument:

ENCODEDMESSAGE="$(php -r 'echo rawurlencode($argv[1]);' -- "$MESSAGE")"
