How to correct the error "Undefined variable"?

Navigation
2

I found two open-source point control systems on the internet: sisponto and wponto . But they are making several mistakes. Some I have corrected, of the type that did not give space or lack semicolon, but others do not understand, like this one.

The complete error is:

The reason why you can not access the variables is because the short_open_tags option is by default off and you are using this option to insert php into html.

Php can be inserted into the html in several ways:

a standard 

<?php echo "olá mundo" ?>

short tags (needs to be enabled); 

<? echo "olá mundo" ?> ou evitando o comando echo <?=$var ?>

ASP style (needs to be enabled); 

<% echo "olá mundo" %>

style script 

<script language="php">
 echo "olá mundo";
</script>

If you do not, you can go to php.ini to enable short tags or change your code 

<meta name="Keywords" content="<?=$_PALAVRAS?>" />

for 

<meta name="Keywords" content="<?php echo $_PALAVRAS ?>" />
