Error reporting will have not included notices on the previous server which is why you haven’t seen the errors.
You should be checking whether the index s
actually exists in the $_GET
array before attempting to use it.
Something like this would be suffice:
if (isset($_GET['s'])) {
if ($_GET['s'] == 'jwshxnsyllabus')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml', '../bibliographies/jwshxnbibliography_')\">";
else if ($_GET['s'] == 'aquinas')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">";
else if ($_GET['s'] == 'POP2')
echo "<body onload=\"loadSyllabi('POP2')\">";
} else {
echo "<body>";
}
It may be beneficial (if you plan on adding more cases) to use a switch
statement to make your code more readable.
switch ((isset($_GET['s']) ? $_GET['s'] : '')) {
case 'jwshxnsyllabus':
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml', '../bibliographies/jwshxnbibliography_')\">";
break;
case 'aquinas':
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">";
break;
case 'POP2':
echo "<body onload=\"loadSyllabi('POP2')\">";
break;
default:
echo "<body>";
break;
}
EDIT: BTW, the first set of code I wrote mimics what yours is meant to do in it’s entirety. Is the expected outcome of an unexpected value in ?s=
meant to output no <body>
tag or was this an oversight? Note that the switch will fix this by always defaulting to <body>
.
