Printing out info from a form

[hotrod57]

I have this php function that reads a text file for input to create a form. I am trying to get the form to print out the data on a separate page, but all I get is a blank page. Am I calling the page correctly, or is this even possible to do?

[PHP]<form action="phpform.php" method=POST>
<?php
$field=array();
$type=array();
$lines = file('test_read.txt');
foreach ($lines as $line) {
list($mytype, $name, $option) = explode("=", $line);
$name = htmlentities(trim($name));
if(isset($option))
$field[$name][]=htmlentities(trim($option));
else
$field[$name]='nooptions';
$type[$name]=trim($mytype);
}

foreach ($field as $name => $options) {

switch($type[$name]) {

case 'label':
print ("<p>$name<br>\n");
break;

case 'checkbox':
print ("<input type=\"checkbox\" name=\"$name\" id=\"$name\" value=\"true\"><label for=\"$name\">$name</label>\n");
break;

case 'radio_button':
print ("<p>$name<br>\n");
foreach($options as $value)
print ("<input type=\"radio\" name=\"$name\" id=\"$name-$value\" value=\"$value\"><label for=\"$name-$value\">$value</label>\n");
break;

case 'comment_box':
print ("<p><label for=\"$name\">$name</label><br>\n");
print ("<p><textarea id=\"$name\" name=\"$name\" rows=\"4\" cols=\"50\"></textarea>\n");
break;

case 'textbox':
print ("<p><label for=\"$name\">$name: </label><input type=\"text\" id=\"$name\" name=\"$name\">\n");
break;

case 'dropbox':
print ("<p><label for=\"$name\">$name: </label><select name=\"$name\" id=\"$name\"><option></option>\n");
foreach($options as $value)
print ("<option value=\"$value\">$value</option>\n");
print ("</select>");
break;
}
}
print ("<p><input type=submit name=submit value=\"SUBMIT\"></form>\n");
print ("<input type=reset value=\"Reset\">\n");
?>
</form>[/PHP]


Text File (just in case):

title = Test Form
label = Choose One of These
checkbox = shoe
checkbox = hair
radio_button = Choose One = 3
radio_button = Choose One = 6
comment_box = Comments
dropbox = Select = 18-29 
dropbox = Select = 30-49 
dropbox = Select = 50-75
textbox = Please type your name

Your form is working fine, right? So now you need to POST the user inputs to the "phpform.php" and print them. Could you please tell us which part is not working, or what is this blank page?

Sorry. The form works fine, except for the reset button. And now that you mention the POST, I guess it makes sense why it's not showing any output. The blank page is "phpform.php." But I guess it wouldn't show anything if I don't put the POSTs in it.

Well the reason is Like this; after fetching the form element properties from the text file, your first page will print like this;

<form action="phpform.php" method=POST>
<p>Choose One of These<br>
<input type="checkbox" name="shoe" id="shoe" value="true"><label for="shoe">shoe</label>
<input type="checkbox" name="hair" id="hair" value="true"><label for="hair">hair</label>
<p>Choose One<br>
<input type="radio" name="Choose One" id="Choose One-3" value="3"><label for="Choose One-3">3</label>
<input type="radio" name="Choose One" id="Choose One-6" value="6"><label for="Choose One-6">6</label>
<p><label for="Comments">Comments</label><br>
<p><textarea id="Comments" name="Comments" rows="4" cols="50"></textarea>
<p><label for="Select">Select: </label><select name="Select" id="Select"><option></option>
<option value="18-29">18-29</option>
<option value="30-49">30-49</option>
<option value="50-75">50-75</option>
</select><p><label for="Please type your name">Please type your name: </label><input type="text" id="Please type your name" name="Please type your name">
<p><input type=submit name=submit value="SUBMIT"></form>
<input type=reset value="Reset">
</form>

On the phpform.php side, you can print the form inputs in this way,

echo $_POST['Comments'];
 

BUT, you won't be able get the form input for this field;

<input type="text" id="Please type your name" name="Please type your name">

Like this

echo $_POST['Please type your name'];

Problem is with the white spaces on the form "field Name" property.

but After changing this line on the text file
textbox = Please_type_your_name

you can get the out put like this'

echo $_POST['Please_type_your_name'];

is this clear?
