confused with echo

[j0seph]

Hi,

 

How would i put <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> within an echo ' '; statement without the characters conflicting?

You need to use string concatenation:

<?php
echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
?>

Cheers ken i'l check it out!

Ok that seems to be good but the debugger now picks up the next line in the echo

<input type="text" name="username" size="10" maxlength="20" value="<?php if (isset($_POST['username'])) echo $_POST['username']; ?>" />

Do i have to stop the echo at the end of value=" then restart it after the end of the statement?

 

My full code is this;

<form action="' . $_SERVER['PHP_SELF'] . '" method="post">
<fieldset>
<p><b>User Name:</b> <input type="text" name="username" size="10" maxlength="20" value="<?php if (isset($_POST['username'])) echo $_POST['username']; ?>" /></p>
<p><b>Password:</b> <input type="password" name="password" size="20" maxlength="20" /></p>
<div align="center"><input type="submit" name="submit" value="Login" /></div>
</fieldset></form>

You should write it like:

<?php
echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
?>
<fieldset>
<p><b>User Name:</b> <input type="text" name="username" size="10" maxlength="20" value="<?php if (isset($_POST['username'])) echo $_POST['username']; ?>" /></p>
<p><b>Password:</b> <input type="password" name="password" size="20" maxlength="20" /></p>
<div align="center"><input type="submit" name="submit" value="Login" /></div>
</fieldset></form>

Thanks again Ken but the login form is nested within an php IF and ELSE statement if the user is not logged in then displayed the login form. However this means the form has to be within an echo statement??

 

<div id="Account">
<?php 
if (isset($_SESSION['user_id']) AND (substr($_SERVER['PHP_SELF'], -10) != 'logout.php')) {
echo '<strong>Account Options</strong><br />
<a href="logout.php">Logout</a><br />
<a href="change_password.php">Change Password</a><br />
<a href="update_details.php">Update Details</a><br />
';
} else {
echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">
';

}

 

Login form needs to be within the else { } but debugger throws up errors..

sorry for incorrect info

Please post all of you code as it is getting confusing as to where this "echo" statement is supposed to go.

echo "<div id=\"Account\">";

if (isset($_SESSION['user_id']) AND (substr($_SERVER['PHP_SELF'], -10) != 'logout.php')) 
{
echo "
          <strong>Account Options</strong><br />
          <a href=\"logout.php\">Logout</a><br />
          <a href=\"change_password.php\">Change Password</a><br />
          <a href=\"update_details.php\">Update Details</a><br />
           ";
} else {
echo "
          <form action=\"$_SERVER['PHP_SELF']\" method=\"post\">
           etc...             
            ";
}

 

That should do. I tend to echo all html to the screen, that way variables don't interfere. Just make sure you do   \"   insted of just ".

hmm this still throws up errors JParishy

 

<form action=\"$_SERVER['PHP_SELF']\" method=\"post\">

 

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/joea8764/public_html/testing/html/includes/footer.html on line 24
