using return

crawfd

I want to intergrate some php code beneath a return. How do I format the php code so that it runs under the return....


return "<form name=\"form2\" method=\"post\" action=\"home.php?page=manage&action=entries\"><select name=\"sort\" style=\"font-size: 11px; font-weight: bold; color: 000000;\" onchange=\"document.forms['form2'].submit()\">

PHP code - how do I seperate syntax from return? ";

What on earth???
You're making no sense man
/Bubble slaps crawfd to bring him back into the real world
😃
What are you trying to do. Can you show us the code for your function?

you can do it the same way you would concatenate echo's or something.
for example:

return "<a href=\"http://www.somewhere.com\">link</a>" . strtoupper("hello") . " <b>" . date("Ymd") . "</b><br>";

Ouch!!! (crawfd slapped in a frenzy). I'll get out my nutcruncher...

This format is giving me an error below:


return "<form name=\"form2\" method=\"post\" action=\"home.php?page=manage&action=entries\"><select name=\"sort\" style=\"font-size: 11px; font-weight: bold; color: 000000;\" onchange=\"document.forms['form2'].submit()\">
		" . if($_GET['sort'] == 1) { echo "<option selected value=\"1\">Sort by Date</option>"; } else { echo "<option value=\"1\">Sort by Date</option>"; } . "

";

You can't generally put logic in a string like that. There is one exception, the ternary operator.

//option one ternary operator
return "<form name=\"form2\" method=\"post\" action=\"home.php?page=manage&action=entries\"><select name=\"sort\" style=\"font-size: 11px; font-weight: bold; color: 000000;\" onchange=\"document.forms['form2'].submit()\"> 
        " . ($_GET['sort'] == 1?"<option selected value=\"1\">Sort by Date</option>":"<option value=\"1\">Sort by Date</option>");

//option two variable
$var="<form name=\"form2\" method=\"post\" action=\"home.php?page=manage&action=entries\"><select name=\"sort\" style=\"font-size: 11px; font-weight: bold; color: 000000;\" onchange=\"document.forms['form2'].submit()\"> 
        ";
if($_GET['sort'] == 1) {
  $var.=?"<option selected value=\"1\">Sort by Date</option>";
} else {
  $ar.="<option value=\"1\">Sort by Date</option>";
}
return $var;

Many people don't like the ternary operator because it can make code difficult to read but like it, maybe I need a slap too 😃

ok,
unfortunately you wont be able to use an if statement in there, or an echo.
you will have to do the if's before the return and then assign the results to a variable and then include the variables in the return concatenation.

if ($_GET['sort'] == 1) {
$sort = "<option......";
} else {
$sort = "<option.....";
}

return "<html code>" . $sort . "<more html>";

what if i just use print instead of return ? ...actually that way I could eliminate the use of memory resources just a tad because it's not using the functino I created...

You still can't put logic inline on string concatonations. Why can't you use an if else?
