Yes. You can acheive that with the combination of PHP<\/strong> and JQUERY<\/strong><\/p>\n

Let’s say this is your first page<\/p>\n

<form action=\"secondPage.php\" method=\"post\">\n    <select id=\"men\" class=\"select_class1\" name=\"subselector\">\n        <option value=\"\">Choose an Item<\/option>\n        <option value=\"tsm\">T-Shirt<\/option>\n        <option value=\"lsm\">Long Sleeve<\/option>\n        <option value=\"tankm\">Tank Top<\/option>\n    <\/select>\n    <input type=\"submit\" value=\"submit\" \/>\n<\/form>\n<\/code><\/pre>\n
Then this would be your secondPage.php<\/code><\/p>\n
<?php\n    $subselector = $_POST['subselector'];\n?>\n<form action=\"anotherPage.php\" method=\"post\">\n    <select id=\"men\" class=\"select_class1\" name=\"subselector\">\n        <option value=\"\">Choose an Item<\/option>\n        <option value=\"tsm\">T-Shirt<\/option>\n        <option value=\"lsm\">Long Sleeve<\/option>\n        <option value=\"tankm\">Tank Top<\/option>\n    <\/select>\n    <input type=\"submit\" value=\"submit\" \/>\n<\/form>\n\n<!-- Now using jQuery to prevent the form from submitting if only the previous selected value doesn't correspond with the present selected value -->\n<!-- don't forget to include your jQuery library here -->\n\n<script>\n    $('form').submit(function(e){\n        prevSelVal = \"<?php echo $subselector; ?>\";\n        presentVal = $('select').val();\n        if(prevSelVal !== presentVal){\n            e.preventDefault();\n            alert('Your Previous Selected Value must Correspond With Your Present Selected Value');\n        }\n    });\n<\/script>\n<\/code><\/pre>\n<\/p><\/div>\n
