php code help (greeting tree)

isuckat_php · April 24, 2010

Help is greatly appreciated. I am working on a code that needs to have the capabilities as this link:

http://athena.ecs.csus.edu/~cs010142/Greeting_tree.php

Exclude the background color and the blinking. I think there is away to set up arrays to make it do this but having difficulty. This is my code so far:

<?php

/*

Your brief description of this program which may include input, output, requirements, and your design highlights

*/

include_once("gt_functions.php");

# MAIN-PROGRAM

$title = "The Greeting Trees";

html_begin ($title, $title);

if ($submit)

{

$size=$_POST['size'];

$tree=$_POST['tree'];

$type=$_POST['type'];

if (($size == "") || (!$tree))

{

echo("<font face=\"Tahoma\" size=\"2\" color=\"#FF0000\"><b>Oops, you forgot

to supply some information. </b></font><br>");

}

else if ((!ereg("[0-9]",$size))

{

echo("<font face=\"Tahoma\" size=\"2\" color=\"#FF0000\"><b>Please restrict

your input to only numbers.</b></font><br>");

}

else if (($size < "12")|| ($size > "24"))

{

echo("<font face=\"Tahoma\" size=\"2\" color=\"#FF0000\"><b>Out of range</b></font><br>");

}

if else (!$type)

{

echo "<font face=\"Tahoma\" size=\"2\" color=\"#FF0000\"><b>Please select tree type. </b></font><br>");

}

else

{

//set up the data in a 2-dimensional array to mark the background

$A =array(array("0","0","0","0","0","0","0","0","0","0","0"),

array("0","0","0","0","0","0","0","0","0","0","0"),

array("0","0","0","0","0","0","0","0","0","0","0"));

//this array A is 11x11, therefore the center of a row is 5

$N = 11;

$center = 5;

//mark tree leaves

for ($i=0; $i < 5; $i++)

{

for($j= ($center - $i); $j<= ($center + $i); $j++)

{

$A[$i+2][$j]= "*";

}

//mark tree trunk

for ($i = 7; $i < 10; $i++)

{

$A[$i][$center] = "*";

}

//display elements of the array in colors of the tree type

for ($i=0; $i< $N; $i++)

{

for($j=0; $j< $N; $j++)

{

DisplayChar ($type, $A[$i][$j]);

}

echo "<BR>";

}

DisplayGreeting($type);

}

//Form to collect user input: one of the 3 greeting tree types

?>

<p>Please enter a tree size between 12 and 24:</p>

<p>Select tree type:</p>

<input type="radio" name="tree" value="Holiday" /> Holiday

<input type="radio" name="tree" value="SacState" /> SacState

<input type="radio" name="tree" value="Suprise" /> Suprise

<br/>

</FORM>

<? html_end () ?>

This is my gt_functions so far( it is not much):

<?php

# A collection of functions that will be included in Greeting_tree.php

function html_begin ($title, $header)

print ("<HTML>\n");

print ("<HEAD>\n");

if ($title)

print ("<TITLE>$title</TITLE>\n");

print ("</HEAD>\n");

print ("<BODY bgcolor=\"#FFFF9C\">\n");

if ($header)

print ("<H2>$header</H2>\n");

}

function html_end ()

{

print ("</BODY></HTML>\n");

}

function DisplayChar ($type, $char)

//display leave color when $char = "*" and background color when $char = "0" according to given tree type

{...}

function DisplayGreeting ($type)

//display greeting message according to given tree type

{...}

?>

Thank you for reading. Again help is much appreciated!
