W3 Schools validation error with POSTBACK and buttons? - postback

Question

This line of code is meant to use POSTBACK:
<form action = "<?php echo $_SERVER["PHP_SELF"];?>" method="post" />
i keep getting these errors:
Line 73, Column 46: an attribute value literal can occur in an attribute specification list only after a VI delimiter
Line 73, Column 47: character data is not allowed here
What exactly is wrong with the code to bring up these errors???
And i have to use this particular method to get full marks.
Also with this code:
<input type="password" name="password" id="password" size="" maxlength="20" />
it keeps bringing up this error:
Line 78, Column 78: document type does not allow element "input" here; missing one of "p", "h1", "h2", "h3", "h4", "h5", "h6", "div", "pre", "address", "fieldset", "ins", "del" start-tag
Help?

Answer 1

From the code you have provided I would say that your input tags are not inside a "container" tag. (your p's, div's, span's etc)
wrap your inputs in one of those and it should remove that validation message:
<form action="<?php echo $_SERVER["PHP_SELF"];?>" method="post">
<p> <!-- CONTAINER TAG FOR VALIDATION -->
Checkbox: <input type="checkbox" name="checktest" value="on"
title="checkbox sample"><br>
RadioButton1: <input type="radio" name="rbtest" value="one"
title="radio button1 sample"><br>
RadioButton2: <input type="radio" name="rbtest" value="two" checked="checked"
title="radio button2 sample"><br>
Text: <input type="text" name="texttest" title="text input sample"><br>
Password: <input type="password" name="passtest" title="pwd sample"><br>
<input type="submit" value="Send"> <input type="reset">
</p>
</form>
Regarding your other messages, this is what the W3C documentation states about the errors you are receiving:
Line 73, Column 46:
111: an attribute value literal can occur in an attribute specification list only after a VI delimiter
Have you forgotten the "equal" sign marking the separation between the attribute and its declared value? Typical syntax is attribute="value".
As mentioned you should not have the space between action and =
Line 73, Column 47:
63: character data is not allowed here You have used character data
somewhere it is not permitted to appear. Mistakes that can cause this
error include:
putting text directly in the body of the document without wrapping it
in a container element, or forgetting to
quote an attribute value (where characters such as "%" and "/" are
common, but cannot appear without surrounding quotes), or using
XHTML-style self-closing tags (such as ) in HTML 4.01 or
earlier. To fix, remove the extra slash ('/') character.
This one is probably because you are self-closing the form tag
change it to:
<form action="<?php echo $_SERVER["PHP_SELF"];?>" method="post">
(replace the /> with >)
