RE: [PHP] programming the onclick() event in an anchor
You can place form tags around the anchors and use hidden tags and send via post so the variable is not obvious. A user reading the source would see this though... echo form name=\form1\ action=\https://this.site.com/somePage.php\; method=\post\\n; echo a onClick=\this.form.submit();\SomeLinkText/a\n; echo input type=\hidden\ name=\variable\ value=\.$value.\\n; echo /form\n; I'm not sure off the top of my head if the anchor tag must have any other description. You might be able to use onChange instead of onClick to include selection by using the keyboard, but I'm not sure if the anchor tag responds to onChange. You'd have to try it out.

Re: [PHP] programming the onclick() event in an anchor [FIXED]
Evan, Thank you for responding - as a newbie to PHP, HTML, and JavaScript, the cookie approach is a little too complex for me. However, after googling some more, I came across the following approach which seems to be simple and works well: (a) enclose the result table within a form, specifying the form name as results, the post method, and action as the page url to be loaded when the anchor is clicked. (b) insert a hidden field (seqnum) within the form. (c) In the php code which builds the table, for the anchor link, use the following code: ($seqno is the data to be passed) print a href=\javascript://\ onclick=\document.results.seqnum.value=$seqno;document.results.submit();\; Result: $HTTP_POST_VARS['seqnum'] will be set to the sequence number. The only downside to this method seems to be that the visited anchors do not change color. Can anyone suggest how to fix that?
