Functions and forms

cjack83 · February 25, 2014, 7:56pm

Just learning about functions and need help understanding this to put it all together. Below is what I have so far.

I created a form and now working on PHP portion. This will return an html web page. I will make it pretty later, just trying to understand this portion. Please look at the comments to understand what each function does. Thank You for any help!

[php]<?php
pagemain();
pageheader();
pagebody();
pagefooter();

//gathers all information and calls all other functions. Not sure how to do this.

function pagemain(){

}

/pageheader will create top html code, including header section.
It will have user write title of page and choose background color/

function pageheader(){
global $page_Title;
global $HTML;
global $HTML2;
global $bg_Color;

$HTML +="$page_Title";
$HTML2 +=“background-color: $bg_Color>”;

}

//pagebody will have welcome title and welcome statement. Does NOT close body section

function pagebody() {
global $w_Title;
global $statement;
global $HTML;

$HTML +="$w_Title
$statement
";

}
//footer information will have footer and close body section and all other html tags

function pagefooter(){
global $footer;
global $HTML;

$HTML +="";

}

//pulled in from the form

$page_Title = filter_input(INPUT_POST, “page_Title”);
$bg_Color = filter_input(INPUT_POST, “bg_Color”);
$w_Title = filter_input(INPUT_POST, “w_Title”);
$statement = filter_input(INPUT_POST, “statement”);
$footer = filter_input(INPUT_POST, “footer”);

?>
[/php]

I’m really not sure what you are trying to accomplish…

If you want to display the HTML page I think all you need to do is add an

[php]echo HTML; [/php]

to your code

[php] <?php
pagemain();
pageheader();
pagebody();
pagefooter();

echo HTML;

//gathers all information and calls all other functions. Not sure how to do this.

function pagemain(){

}

/pageheader will create top html code, including header section.
It will have user write title of page and choose background color/

function pageheader(){
global $page_Title;
global $HTML;
global $HTML2;
global $bg_Color;

$HTML +="$page_Title";
$HTML2 +=“background-color: $bg_Color>”;

}

//pagebody will have welcome title and welcome statement. Does NOT close body section

function pagebody() {
global $w_Title;
global $statement;
global $HTML;

$HTML +="$w_Title
$statement
";

}
//footer information will have footer and close body section and all other html tags

function pagefooter(){
global $footer;
global $HTML;

$HTML +="";

}

//pulled in from the form

$page_Title = filter_input(INPUT_POST, “page_Title”);
$bg_Color = filter_input(INPUT_POST, “bg_Color”);
$w_Title = filter_input(INPUT_POST, “w_Title”);
$statement = filter_input(INPUT_POST, “statement”);
$footer = filter_input(INPUT_POST, “footer”);

?>[/php]

I’ve cleaned up my code and changed the $HTML to $PAGE and added the print $PAGE but all it prints is a 0. I’ve been looking at this code so long, maybe some fresh eyes will spot it!

[php]

<?php //gathers all information and calls all other functions function pagemain(){ pageheader(); pagebody(); pagefooter(); } /*pageheader will create top html code, including header section. It will have user write title of page and choose background color*/ function pageheader(){ global $page_Title; global $bg_Color; global $PAGE; $PAGE +="$page_Title background-color: $bg_Color;"; } //pagebody will have welcome title and welcome statement. Does NOT close body section function pagebody() { global $w_Title; global $statement; global $PAGE; $PAGE +="

$w_Title

\n

$statement

"; } //footer information will have footer and close body section and all other html tags function pagefooter(){ global $footer; global $PAGE; $PAGE +="

$footer

"; } //pulled in from the form $page_Title = filter_input(INPUT_POST, "page_Title"); $bg_Color = filter_input(INPUT_POST, "bg_Color"); $w_Title = filter_input(INPUT_POST, "w_Title"); $statement = filter_input(INPUT_POST, "statement"); $footer = filter_input(INPUT_POST, "footer"); pagemain(); print $PAGE; ?>[/php]

I figured it out for you, I take it you’re like me and you have a different development background.

The syntax below is .NET syntax… with the += but in php it should be .= to combine strings.

[php]$PAGE +="$page_Title
background-color: $bg_Color;";[/php]

Like this:

[php]$PAGE .="$page_Title
background-color: $bg_Color;";[/php]

cjack83 · February 26, 2014, 9:06pm

changed to .= and still not working…

Topcoder · February 26, 2014, 9:11pm

Change all of them to that… not just the one I posted. Then right click and view source on the page and you will see your html.

benanamen · February 26, 2014, 11:27pm

Your going about the whole thing the wrong way. You need to include files, not put everything in functions.

[code]
<?php include_once('./includes/header.php'); ?>

     <div id="body">
        <?php include_once('./includes/body.php'); ?>
     </div>

     <div id="footer">
        <?php include_once('./includes/footer.php'); ?>
     </div>[/code]

@ topcoder - Yes I did change all of them to " .=" and viewed my source code and no html just the “0”

@Kevin Rubio - I know your right but I would really like to figure out why this isn’t working first. I’m learning about functions and that’s why they are in the code.

Topcoder · February 27, 2014, 3:50am

Can you post your changed code please.

cjack83 · February 27, 2014, 3:58am

Thanks for looking at it again.

[php]<?php

//gathers all information and calls all other functions
function pagemain(){
pageheader();
pagebody();
pagefooter();
}

/pageheader will create top html code, including header section.
It will have user write title of page and choose background color/
function pageheader(){
global $page_Title;
global $bg_Color;
global $PAGE;

$PAGE .="$page_Title
background-color: $bg_Color;";
}

//pagebody will have welcome title and welcome statement. Does NOT close body section
function pagebody() {
global $w_Title;
global $statement;
global $PAGE;

$PAGE .="

$w_Title

\n

$statement

";
}

//footer information will have footer and close body section and all other html tags
function pagefooter(){
global $footer;
global $PAGE;

$PAGE .="

$footer

";
}

//pulled in from the form
$page_Title = filter_input(INPUT_POST, “page_Title”);
$bg_Color = filter_input(INPUT_POST, “bg_Color”);
$w_Title = filter_input(INPUT_POST, “w_Title”);
$statement = filter_input(INPUT_POST, “statement”);
$footer = filter_input(INPUT_POST, “footer”);

pagemain();
print $PAGE;

?>

[/php]

You need to change all the $PAGE .=
to
echo

cjack83 · February 27, 2014, 4:17am

Didn’t work and checked page source - no html.

Topcoder · February 27, 2014, 2:40pm

I tested your code it works fine for me … when I view the source… I see this…

[php]
background-color: ;

      <p></p><h3></h3></body></html>[/php]

This is not what you might expect to see, but it’s what I expect to see based on the code. But as you can see it doesn’t print a “0”

You can look at your code run here…

http://phphelp.com/phpfunction.php

Right click and view source…

benanamen · February 27, 2014, 3:11pm

Start from here with basic output from each function.

[php] <?php
function pagemain()
{
pageheader();
pagebody();
pagefooter();
}

function pageheader()
{
echo “Header Output
”;
}

function pagebody()
{

echo "Body Output<br />";
}

function pagefooter()
{

echo "Footer Output";
}

pagemain();
?>[/php]

cjack83 · March 1, 2014, 2:59am

echo “Header Output
”; prints “Header Output”

Am I misunderstanding you?

benanamen · March 1, 2014, 3:39am

No. It was just to display some output from each function. Build on it one step at a time to get what you want.
