@NogDogJul 15.2010 — #I suppose the "best" solution would depend on how much time/work you can put into it. Perhaps the quickest would be to do an ob_start() at the beginning of the main script, then at whatever point you have all the data you need, do a ob_get_clean() and assign its result to a variable. Then you can use str_replace() or preg_replace() to change the values of the title, keywords, etc.; then echo that variable to output the page to that point.
The opposite end of the spectrum would be to implement a MVC framework such as CodeIgniter, CakePHP, etc. or a templating system such as Smarty.
Perhaps in between would be to functionalize your header stuff so that it can take parameters for the title and other variable data, then call the functions from the content page once it has the data? @NogDogJul 16.2010 — #This is probably a good illustration of why MVC and similar patterns try to separate the presentation layer (i.e. the View) from the other processing (i.e. the Model and Controller).
Perhaps you can at least split your "content" into two files: one that does the "business process" and populates variables and arrays based on the request type/data, then you can include the header, content-output, and footer files, allowing them to access that data.
Resequencing echo statements and includes: suggestions needed
Dear PHP-ologists,
For a variety of reasons (including legacy code) I have a number of websites that (in a nutshell) more or less do the following:
In index.php:
include (‘templates/header.php’);
include (‘content/homepage.php’);
include (‘templates/footer.php’);
In header.php:
echo $headerstuff_line1 . “n”;
echo $headerstuff_line2 . “n”;
echo $headerstuff_line3 . “n”;
# etc…
(and footer.php works similarly of course).
In home.php:
echo ‘<h1>Hello world</h1>’ . “n”;
echo ‘Content line 1…’ . “n”;
echo ‘Content line 2…’ . “n”;
echo ‘Content line 3…’ . “n”;
# etc…
And home.php (or any other page that gets included here, depending on the parsing of query parameters) may contain other stuff as well, such as SQL queries, invocation of E-mail / captcha / form / other classes, and what not. Crude but effective.
But now I am faced with a need to modify the page header include file on the basis of variables that get defined in the content include file. For example in home.php there could be something like
$pageTitle = ‘Home’;
which would then have to be used in the header.php include, as in:
echo ‘<title>’ . $pageTitle . </title>’ . “n”;
Which means that I have no shot myself in the foot, since the header has been included (and has executed it’s ‘echo’ statements) before the content file (with the declarations needed in the header) is loaded up only after that.
Fixing it involves breaking my straightforward process flow – i.e. I would have to put the statements that output the header into the content include (e.g. home.php) which I find highly inelegant… Or even worse, I would have to store entire chunks of HTML content in large memory-consuming variables, manipulate them later, and output them only after modification, which also breaks my straightforward process flow _and
So. Suggestions anyone? Clearly I need to so something very simple and sensible here, but i just can’t see it. Any idea’s would be appreciated!
