You need to state what error you are getting. I see nothing in that which would cause an error - but I'm positive it won't produce the results you are wanting.

You open the string with a single quote and close it with a single quote. Plus, there are no single quotes inside the string (if there were they would just need to be escaped). So, the string is properly defined. However inside the string I see what I assume are PHP variables:

Date:  $date <br/>

PHP variables are not interpreted inside single quoted strings, but they are within double quoted strings (there are also the nowdoc and heredoc methods of defining strings that work the same, respectively). You should read this page: http://php.net/manual/en/language.types.string.php especially the section about variable parsing: http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing

So, you can do a few different things:

1. Continue defining the string using single quotes. You would need to close/reopen the sting to append the variables such as:

$var = 'Date: ' . $date . '<br>';

2. Change the string to be defined by double quotes and do one of the following:

a. Escape all instances of double quotes inside the string

<div class=\"content\">

b. Change all instances of double quotes to single quotes inside the string

<div class='content'>

Many times you cannot do just a or just b, but have to use a combination of both. For example, if you were trying to display a measurement of 4 feet, 5 inches it should be displayed as follows: 4'5". So, you would have to escape which ever one was used to define the string. You can even mix and match different quotes for different parts of the strings. But, I think it's better to stick to one style - at least until you really understand it all and know why one method is better than another for a specific situation.

rubyarat2010 · July 9, 2012

rubyarat2010 · July 9, 2012

mikosiko works now but now the php variables in the html dont work?

xyph · July 9, 2012

Strings surrounded by single quotes won't evaluate variables within them.

You need double quotes, and you need to RTFM.

http://php.net/manual/en/language.types.string.php

They go into huge detail, and provide many examples.

Psycho · July 9, 2012

but thats not in the html?

Because the error you received had nothing to do with the multi-line HTML string variable! The error told you what line the error was on.

rubyarat2010 · July 9, 2012

sorry but this didint work

Author: "$author"

Date: " $date"

"$body"

rubyarat2010 · July 9, 2012

<?php echo $author ?>

this didint work either.

jcbones · July 9, 2012

Psycho went into great detail in his first reply. Please don't waste that post, as the info is very accurate. Follow the first example, marked by 1.(one), and it will work.

PHP variables are not interpreted inside single quoted strings, but they are within double quoted strings (there are also the nowdoc and heredoc methods of defining strings that work the same, respectively)........

So, you can do a few different things:

1. Continue defining the string using single quotes. You would need to close/reopen the sting to append the variables such as:
$var = 'Date: ' . $date . ' ';
......

What part of # 1 you didn't understood?... are you even paying attention to what the people trying to helping you had wrote for you?... doesn't look like.

rubyarat2010 · July 9, 2012

I did even tried puting periods like he showed

Author:'$author; '

Date: '$date;'

' $body;'

Adam · July 9, 2012

There's not a single period (".") in that bit of code you just posted?

rubyarat2010 · July 10, 2012

Ok i got it one other thing i assighn the header at the end but it gives me this error

Warning: Cannot modify header information - headers already sent by (output started at /home/zendavis/public_html/insert.php:2) in /home/zendavis/public_html/insert.php on line 76?

jcbones · July 10, 2012

Did you read the manual for header? I ask because the second line under the function description is:

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include, or require, functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.
