problem with echo

[Reaper0167]

this doesn't work

echo '<?php 
	   		 <form name="form1" method="post" action="login.php">
			 <input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
			 <input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
			 <input type="submit" name="submit" id="submit" value="Login">
			 <br />
			 Not registered? <a href="register.php">Register Now!</a>
			 </form>';
  	    		 ?>

but this does work,, what is going on?

<?php
<form name="form1" method="post" action="login.php">
<input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
<input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
<input type="submit" name="submit" id="submit" value="Login">
<br />
Not registered? <a href="register.php">Register Now!</a>
</form>
?>

when i echo out the form i get an error

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in D:\-----\-----\html\------\index.php on line 35

here is line 35

<input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />

should something be different when echoing out the form while using the onfocus

Echo is not inside the php tags. The second code should not work. Try this:

 

<?php 
                echo '<form name="form1" method="post" action="login.php">
             <input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
             <input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
             <input type="submit" name="submit" id="submit" value="Login">
             <br />
             Not registered? <a href="register.php">Register Now!</a>
             </form>';
                ?>

 

This would also work:

 

<?php
echo <<<FORM 
             <form name="form1" method="post" action="login.php">
<input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
<input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
<input type="submit" name="submit" id="submit" value="Login">
<br />
Not registered? <a href="register.php">Register Now!</a>
</form>
FORM;
?>

 

The 2nd is using HEREDOC syntax.

here is the full code for the table i have everything in

<?php // this start tag is not in my code,, just put it there for you
<table width="950" border="0" align="center" cellpadding="0" cellspacing="0">
  <tr>
    <th height="297" scope="col"><div id="header"><img src="images08/header.png" alt="header" width="421" height="47" /></div>
      <div id="apDiv1">
        <?php
        session_start();
        if(isset($_SESSION['auth']))
        {
      	  echo $_SESSION['message'];
        }
        else
        {
      	   echo '<?php 
	   		 <form name="form1" method="post" action="login.php">
			 <input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
			 <input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
			 <input type="submit" name="submit" id="submit" value="Login">
			 <br />
			 Not registered? <a href="register.php">Register Now!</a>
			 </form>';
  	    		 ?>
	}
	    ?>
    </div></th>
  </tr>
</table>
?> // same with this tag

now you can get a better look at why it is not working.

            echo '
                <form name="form1" method="post" action="login.php">
             <input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
             <input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
             <input type="submit" name="submit" id="submit" value="Login">
             <br />
             Not registered? <a href="register.php">Register Now!</a>
             </form>';
                // this was causing an issue?>

 

You had unessarcy <?php tag inside the echo tag. Remove that. Also note you need to remove the ?> The echo statement can be echoed and must be echoed inside php tags and since you are already in php, that was causing an issue.

i removed the php tags.here i what i got.. still an error.

<table width="950" border="0" align="center" cellpadding="0" cellspacing="0">
  <tr>
    <th height="297" scope="col"><div id="header"><img src="images08/header.png" alt="header" width="421" height="47" /></div>
      <div id="apDiv1">
        <?php
        session_start();
        if(isset($_SESSION['auth']))
        {
      	  echo $_SESSION['message'];
        }
        else
        {
      	   echo '<form name="form1" method="post" action="login.php">
			 <input name="username" type="text" id="username" value="User ID" onfocus="this.value='';"  />
			 <input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />
			 <input type="submit" name="submit" id="submit" value="Login">
			 <br />
			 Not registered? <a href="register.php">Register Now!</a>
			 </form>';
  	    }
	    ?>
    </div></th>
  </tr>
</table>

still getting an error with this line

<input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />

Because you have single quotes within a single quoted string. Either escape them or use double quotes.

 

This really is php basics.

[premiso]

The single quotes are causing the issue, they need escaped:

 

            echo '<form name="form1" method="post" action="login.php">
             <input name="username" type="text" id="username" value="User ID" onfocus="this.value=\'\';"  />
             <input name="password" type="password" id="password" value="Password" onfocus="this.value=\'\';" />
             <input type="submit" name="submit" id="submit" value="Login">
             <br />
             Not registered? <a href="register.php">Register Now!</a>
             </form>';

[phpSensei]

You have session_start after the HTML

 

you must call session_start() before anything is outputted to the browser.

[Reaper0167]

don't understand why that would make a difference. here is the code with the onfocus for the text boxes removed. everything loads just fine.

<table width="950" border="0" align="center" cellpadding="0" cellspacing="0">
  <tr>
    <th height="297" scope="col"><div id="header"><img src="images08/header.png" alt="header" width="421" height="47" /></div>
      <div id="apDiv1">
        <?php
        session_start();
        if(isset($_SESSION['auth']))
        {
      	  echo $_SESSION['message'];
        }
        else
        {
      	   echo '<form name="form1" method="post" action="login.php">
			 <input name="username" type="text" id="username" value="User ID"  />
			 <input name="password" type="password" id="password" value="Password"  />
			 <input type="submit" name="submit" id="submit" value="Login">
			 <br />
			 Not registered? <a href="register.php">Register Now!</a>
			 </form>';
  	    }
	    ?>
    </div></th>
  </tr>
</table>

i get the error when the 2 lines are changed to this

 

<input name="username" type="text" id="username" value="User ID" onfocus="this.value='';" />

<input name="password" type="password" id="password" value="Password" onfocus="this.value='';" />

Umm did you look at my post, I escaped the single quotes so you should not get the error.

 

This is really basic php syntax as Thorpe said.

[Reaper0167]

sorry premiso,, i skipped your post,,, my bad

[Reaper0167]

with escaping the single quotes or even using double quotes, i don't get any errors, but when i click on the text field, my initial value is not removed.
