How Do I Insert "for" Loop In Class Module?
Below are three scripts that create one page. The " TopNewsPageTwo.php" script creates an instance, the " HtmlTemplateClass.php" is the class used with the instance script, and the " TopNewsTemplateP2.php" template below displays the output in the browser.
My problem is this: How do I insert a " for" loop so that the output will display on the page (see " TopNewsTemplateP2.php" below for the desired positioning)?
The " for" loop that I'm needing to incorporate into the process is as follows:
$TextBoxes = "$Paragraphs";
for($i=1; $i<=$TextBoxes; $i++)
{
echo "<textarea rows=\"3\" cols=\"40\" name=\"Textfield\"" . "[$i]" ."></textarea><p>" . "\n";
}
What I would like to do is somehow incorporate the " for" loop in the " HtmlTemplateClass.php" class module, if possible, so that I may separate the PHP code from the HTML code.
Does anyone have any suggestions about how I might accomplish my task?
PHP Code:
// -------- TopNewsPageTwo.php ---------------
// Creates an instance "TopNewsPageTwo.php"
// This page receives the "$Year"."$Month"."$Day"."$Number" variables from an input
// form on a previous page, checks them (ref. $CheckReference) to see if there is
// an existing news article in the "TopNews" table. If no article with the same
// reference number in the "TopNews" table then this page creates an instance.
require_once "./conf/config.inc.php";
$CheckReference = "$Year"."$Month"."$Day"."$Number";
$Date = "$Year"."$Month"."$Day";
$TableName = "TopNews";
$Query="SELECT Reference FROM $TableName";
$Result = mysql_db_query ($db_info[dbname], $Query, $db_connection);
while ($Row = mysql_fetch_array($Result))
{
if ($CheckReference === $Row["Reference"])
{
$TakenInUse="That news reference is currently in use. Please make another choice.";
}
}
mysql_close ($db_connection);
if (isset($TakenInUse))
{
echo $TakenInUse;
}else{ // If the $CheckReference variable does not exist in database do the following:
require_once "HtmlTemplateClass.php"; // Include the class.
$page = new HtmlTemplate(); // Create an instance.
$page->IdentifyTemplate ("TopNewsTemplateP2.php"); // Identify the template.
//----------------------
$page->SetParameter ("PAGE_TITLE", "Welcome to OOP!");
$page->SetParameter ("PAGE_CONTENT", "Here is the main part of the page.");
$page->SetParameter ("NEWS_REFERENCE_NUMBER", "$Year"."$Month"."$Day"."$Number");
$page->SetParameter ("MONTH", "$Month"); // Set the month.
$page->SetParameter ("DAY", "$Day"); // Set the day.
$page->SetParameter ("YEAR", "$Year"); // Set the year.
$page->SetParameter ("DATE", "$Year"."$Month"."$Day"); // Set the date.
//----------------------
$page->CreatePage(); // Send the page to the browser.
}
// -------- HtmlTemplateClass.php ---------------
// This is the class that is used with the "TopNewsPageTwo.php" script above.
class HtmlTemplate {
// Set the attributes.
var $Template;
var $Html;
var $Parameters = array();
function IdentifyTemplate ($Template) { // This function sets which template will be used.
$this->Template = $Template;
}
function SetParameter ($Variable, $Value) { // This function sets the particular values.
$this->Parameters[$Variable] = $Value;
}
function CreatePage () { // Read the template into an array, then create a string.
$this->Html = implode ("", (file($this->Template)));
// Loop through all the parameters and set the variables to values.
foreach ($this->Parameters as $Key => $Value) {
$TemplateName = '{' . $Key . '}';
$this->Html = str_replace ($TemplateName, $Value, $this->Html);
}
echo $this->Html;
}
}
// -------- TopNewsTemplateP2.php ---------------
// This is the template that is used with the "TopNewsPageTwo.php" instance
// and the "HtmlTemplateClass.php" class above.
<html>
<head>
<title>{PAGE_TITLE}</title>
</head>
<body><center>
<table border="1" cellspacing="5" cellpadding="5">
<tr><td><p>
<span class="text5">News Reference <b>{NEWS_REFERENCE_NUMBER}</b></span><p>
<form action="PageThree.php" method="post"><p>
<input type="hidden" name="Reference" value="{NEWS_REFERENCE_NUMBER}"><p>
<input type="hidden" name="Month" value="{MONTH}"><p>
<input type="hidden" name="Day" value="{DAY}"><p>
<input type="hidden" name="Year" value="{YEAR}"><p>
<input type="hidden" name="Date" value="{DATE}"><p>
// I need to insert the output from this loop here.
// The $Paragraphs variable is received from a form on a previous page.
$TextBoxes = "$Paragraphs";
for($i=1; $i<=$TextBoxes; $i++)
{
echo "<textarea rows=\"3\" cols=\"40\" name=\"Textfield\"" . "[$i]" ."></textarea><p>" . "\n";
}
// Insert output from loop immediately above.
</form></td></tr><p>
</table>
</center></body>
</html>
//-------------------------
Thanks.
