include question (globals)

pngtest · June 16, 2008

do you need to have registered globals on when you use the include.

i have these pages that i got from a book to teach me to program php i had to change some stuff as it teach's with globals on. but i did not think you would for the include.

I think you it's recommended to disable register globals. Check out this link. And I don't think it is necessary to have register globals on when using "includes".

thanks for that but it does not seem to help. i have the two files where one get variables from the other and prints out basic html tags here

<?php
//import the definition of SuperHTML
include "SuperHTMLDef.php";

//instantiate and use a superHTML page

$s = new SuperHTML("My Super Duper Page!");
$s->setTitle("SuperHTML Demo");
$s->buildTop();

$s->h3("Using the tag method");
$s->tag("i", "This line should be italicized");

$s->h3("adding arbitrary text");
$s->addText("I used the addText method here");

$s->h3("build table from 2d array");
$myArray = array(
  array("English", "Spanish", "Japanese"),
  array("One", "Uno", "Ichi"),
  array("Two", "Dos", "Nii"),
  array("Three", "Tres", "San")
);
$s->buildTable($myArray);

$s->h3("build table row-by-row");
$s->startTable(3);
$s->tRow(array("English", "Greek"), "th");
$s->tRow(array("a", "alpha"));
$s->tRow(array("b", "beta"));
$s->endTable();

$s->h3("build an unordered list");
$s->buildList(array("alpha", "beta", "gamma", "delta"));

$s->h3("build an ordered list");
$s->buildList(array("alpha", "beta", "gamma", "delta"), "ol type = 'a'");

$s->h3("form elements");

$s->addText("<form> \n");
$s->textbox("user name", "Joe");


$s->h3("create select object from associative array");

$numArray = array(
  "1"=>"ichii",
  "2"=>"nii",
  "3"=>"san",
  "4"=>"shi"
);

$s->buildSelect("options", $numArray);

$s->h3("make form elements inside a table!");

$myArray = array(
  array($s->gTag("b","name"), $s->gTextbox("name")),
  array($s->gAddText("address"), $s->gTextbox("address")),
  array($s->gAddText("phone"), $s->gTextbox("phone")),
  array($s->gAddText("favorite number"), $s->gSelect("numbers", $numArray))
);

$s->buildTable($myArray);
$s->submit();

$s->addText("</form> \n");

print $s->getPage();

?>

you would go to this in the browser and it should print tables and other things.

and this is the include.

What exactly is the problem? Register globals has nothing at all to do with the functionality of the include language construct.

hitman6003 · June 17, 2008

You have an incorrectly named function (or you called the wrong one in your page)...

function select($name, $listVals){
    $this->addText($this->gSelect($name, $listVals));
  } // end buildSelect

Should be:

function buildSelect($name, $listVals){
    $this->addText($this->gSelect($name, $listVals));
  } // end buildSelect

Thanks for that sorry i am new at this.... when i go to the demo page you get a whole lot of undefined Variable error's and i don't know what would cause that.

trq · June 17, 2008

when i go to the demo page you get a whole lot of undefined Variable error's and i don't know what would cause that.

That would be caused by using a whole lot of undefined variables. handling variables is often not tought properly in older books. Basically you need to make sure any variables exist prior to trying to use them. eg;

<?php

  if (isset($_POST['foo'])) {
    // $_POST['foo'] is safe to use.

  }

?>

pngtest · June 17, 2008

ok i think i got it but i still get the error

Notice: Undefined variable: temp in /home/jking/public_html/SuperHTMLDef.php on line 175

and can't seem to fix it.

trq · June 17, 2008

Can you post a few lines prior to, including and after line 175.

pngtest · June 17, 2008

here it is

 //form elements
  function gTextbox($name, $value = ""){
    // returns but does not print
    // an input type = text element
    // used if you want to place form elements in a table
    $temp .= <<<HERE
<input type = "text"
       name = "$name"
       value = "$value" />

HERE;
    return $temp;
  } // end textBox

kenrbnsn · June 17, 2008

Don't use ".=", instead use "="

The ".=" assumes the target of the assignment already exists. It doesn't here.

<?php
//form elements
  function gTextbox($name, $value = ""){
    // returns but does not print
    // an input type = text element
    // used if you want to place form elements in a table
    $temp = <<<HERE
<input type = "text"
       name = "$name"
       value = "$value" />

HERE;
    return $temp;
  } // end textBox
?>
