Help is greatly appreciated.
I am generating a multiplication table that runs numbers 2-15 depending on which number the user chooses to input.
The problem is when i input a number it infinetly multiplies the number by 1.
Here is the code:
<?php
// time_table.php - a demo of using functions and include file script
// Get the functions we need for this time table
// Using extension "php" instead of "inc" will prevent others see the code
include_once("tt_functions.php");
# MAIN-PROGRAM
$title = "The Times-Tables";
html_begin ($title, $title);
#Validation of input and then produce the Times-Tables
#
if ($submit)
{
if ($n == ''){
?>
<span style="color:red;"><b>Oops, your forgot to supply info required.
Please correct the problem and try again. </b></span><br/>
<?
}
else if ((!ereg("[0-9]", $n))){
?>
<span style="color:red;">
<b>Please restrict your input to only numbers.</b></span><br/>
<?
}
else if (($n >= 15 ) || ($n < 2)) {
echo "Number Range Error.";
}
else{
//ready to produce the time tables
//function timetable( ) was defined in the included file function_timetable.php
timetable($n);
}
}
// Forms to collect user input
?>
<form method="post" action="time_table.php">
<p><b>Please enter an interger between 2 and 15:</b></P>
<input type='text' name='n' />
<p><input type="submit" name="submit" value="Time Tables" /></P>
</form>
<? html_end () ?>
Here is the tt_functions:
<?php
# A collection of functions to make our time table engineering
# easy to understand. It will be included in time_table.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>$header</H2>\n");
}
# put out final HTML tags for page.
function html_end ()
{
print ("</BODY></HTML>\n");
}
function timetable ($n) {
// Go through each table
for ($table=1; $table<=$n; $table++)
{
print "<p><b>The ".$table ."Times Table</b>\n";
//Produce $n lines for each table
for($counter=1; $counter=$n; $counter++)
{
$answer = $table * $counter;
//Is this an even-number counter?
if ($counter % 2 == 0)
//Yes, so print this line in bold
print "<br><b>$counter x $table = ".
"$answer</b>";
else
//No, so print this in normal face
print "<br>$counter x $table = $answer";
}
}
}?>
Again help is much appreciated. Thank you for taking the time to read this.

for($counter=1; $counter=$n; $counter++)
why are you evaluating if $counter=$n? will it ever =$n when you are assigning the value to it? oh, it always will thats right. If you want less than or equal to you should change it to:
but I'm usually wrong.
