Using POST within SWITCH statement

[stewdizzle]

I am setting up a small site for personal use. It consists of a form that transfers inputed values to an html template. The ouput is code that i can use to quickly post on a website. In the template i have the following code:

<?php $images = $_POST["myRadioButton"];
   switch ($images)
   {
   case 1:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break; 
   case 2:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg"> &nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break;
    case 3:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg">&nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">&nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break;}
   ?>

I want to replace the url with a variable:

$_POST["image1"];

image1 being the field that the url would be entered into. I have done it outside the switch statement and it works fine. Any suggestions?

i dont realy understand what do you mean bt replace the url
somthing like that:
header('Locatio n: $_POST['image1']");
or you want to show $_POST['image1'] in the url like that
http://$_POST['image1']/
please explain

I wouldn't use switch, rather a for- or while-loop.

Can we see the HTML form you are using to submit the data? That way, if it sheds some light on the situation, we may be able to offer a better way to accomplish the task.

This is the code for the start page

<table width="800px"> 
<tr>
<td>
<!--Select how many images and disable unused text boxes-->
<form action="combinedcode.php" method="post">

<input type="radio" name="myRadioButton" value="1" onclick="image1.disabled=false; image2.disabled=true; image3.disabled=true" checked="checked" /> 1 Picture
  
<input type="radio" name="myRadioButton" value="2" onclick="image1.disabled=false; image2.disabled=false; image3.disabled=true" /> 2 Pictures

<input type="radio" name="myRadioButton" value="3" onclick="image1.disabled=false; image2.disabled=false; image3.disabled=false" /> 3 Pictures


<!--Information-->
  
  <p>Enter the Auction Title:
  <input type="text" name="title" cols="50" />
 
  <br />
  <br />
    Enter A Description: 
  <textarea cols="50" rows="10" wrap="soft" name="description"></textarea>
  <br />
  <br />
    Enter the URL for Image 1: <input type="text" name="image1" />
  <br />
  <br />
    Enter the URL for Image 2: <input type="text" name="image2" />
  <br />
  <br />
    Enter the URL for Image 3: <input type="text" name="image3" />
  
  </p> 
  <p>
 <input type="submit" name="submit1" value="Generate Auction Code"/>
  </p>
  
</form>
</td>

</tr>
</table>

This is the output page:

 <center>
 <!--This is the text to copy-->
<textarea cols="100" rows="25" readonly="readonly" wrap="soft" onclick='highlight(this);'>
 <?php require_once('combinedtemp.html'); ?>

</textarea>
<br />
<br />
<!--This is the preview-->
<?php include('combinedtemp.html'); ?> 
</center>

This is the relevant template code with variables:

<div class="float">
  <?php $images = $_POST["myRadioButton"];
   switch ($images)
   {
   case 1:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break; 
   case 2:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg"> &nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break;
    case 3:
     echo '<img src="http://i43.tinypic.com/29z3eyo.jpg">&nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">&nbsp;
           <img src="http://i43.tinypic.com/29z3eyo.jpg">';
     break;}
   ?>

Before using the switch statement I used the below code to pull in the URL from the input page but I couldn't specify how many boxes to pull from:

<a href="<?php echo $_POST["image1"]; ?>" target="_blank"><img height="200" src="<?php echo $_POST["image1"]; ?>" ></a>

I know its not pretty and may not be the most efficient way to write it but I am learning as I create.

the actual site link is http://codegenerator.x10hosting.com/combined.php

[stewdizzle]

I figured it out. I had to echo each part of the image src code seperately: Like i said, not pretty but it gets the job done. If anyone can walk me through making this better i would appreciate the learning experience.

<?php $images = $_POST["myRadioButton"];
   switch ($images)
   {
   case 1:
     echo '<img src="';
     echo $_POST["image1"]; 
     echo '">';
     break; 
   case 2:
     echo '<img src="';
     echo $_POST["image1"]; 
     echo '"> &nbsp;';
     echo '<img src="';
     echo $_POST["image2"]; 
     echo '">';
     break;
    case 3:
     echo '<img src="';
     echo $_POST["image1"]; 
     echo '"> &nbsp;';
     echo '<img src="';
     echo $_POST["image2"]; 
     echo '"> &nbsp;';
     echo '<img src="';
     echo $_POST["image3"]; 
     echo '">';
     break;}
   ?>

[CODE=PHP]
case 1:
echo '<img src="';
echo $_POST["image1"];
echo '">';
break;
[/CODE]
write it like that:
[CODE=php]
case 1:
echo "<img src='$_POST[\'image1\']'>";
break;
[/CODE]
double quotes evaluate the variables

I tried that but i got this error

<br />
<b>Parse error</b>: syntax error, unexpected T_ENCAPSED_AND_ WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in <b>/home/sbmccal/public_html/template.html</b> on line <b>95</b><br />

[Dormilich]

you could also try

echo '<img src="', $_POST['image1'], '">";

[Markus]

You might also try

echo "<img src='{$_POST['img']}' />";
