Guest kilbad Posted October 17, 2006 Share Posted October 17, 2006 Most pages on my website are generated with three [i]include[/i] commands, such that the header and footer are the same for all::[code]include 'header.php';include "$some_unique_page.php";include 'footer.php';[/code]In my header, I want to have the following code::[code]<title><?php echo "$page_title_of_unique_content"; ?></title>[/code]..and I want the $page_title_of_unique_content variable to be defined in the $some_unique_page.php file.[b]Question:: Is it possible somehow echo this variable in the header title when it is being defined later on in the included script?[/b] Quote Link to comment Share on other sites More sharing options...
rab Posted October 17, 2006 Share Posted October 17, 2006 No, not if it is already defined Quote Link to comment Share on other sites More sharing options...
Guest kilbad Posted October 17, 2006 Share Posted October 17, 2006 It is not defined already, just later, in the some_unique_page.php Quote Link to comment Share on other sites More sharing options...
obsidian Posted October 17, 2006 Share Posted October 17, 2006 trying to echo a variable before it is defined would be like me expecting you to be able to solve a math problem for me without ever seeing the equation. there is no way PHP knows what to output if a variable has not been defined. why, exactly, can't the title variable be set somewhere else before the header is output?

btherl Posted October 18, 2006 Share Posted October 18, 2006 Smarty templates will solve this problem. It's a big step from standard php to Smarty though.Another option is to buffer your output using ob_start() and related functions. Then you can modify the buffer before displaying it, with str_replace() for example.[code]<? ob_start() ?><title>{PAGE_TITLE}</title>...$output = ob_get_clean();$output = str_replace('{PAGE_TITLE}', $page_title_of_unique_content, $output);print $output;[/code] Quote Link to comment Share on other sites More sharing options...

Guest kilbad Posted October 18, 2006 Share Posted October 18, 2006 Follow-up question (I am new to smarty templates)..[b]With regard to smarty tags (like {PAGE_TITLE} for example, if I leave it undefined within some php document, how can I make it so that nothing is displayed, rather than "{PAGE_TITLE}"?[/b]Restated, in the above example, if {PAGE_TITLE} was undefined, I would want no title displayed, NOT "{PAGE_TITLE}"..Thanks in advance for the help!!Brendan Quote Link to comment Share on other sites More sharing options...
