在 Wordpress 中从表单调用变量以呈现图表

Question

I am trying to use a Wordpress chart generation plugin, but call a variable that the user sets on the page. I've got the chart code in and it works at a rudimentary level and I was able to add a form to the page in which a user could enter a number and submit it, but the PHP code for calling the variable from the form breaks the chart code, I believe because the chart code looks for a ] character to determine where to conclude the chart script.

As follows:

Chart Code: [easychart type="pie" height="100" width="100" title="US Federal Expenditures, 2011 Fiscal Year" groupnames="Unfunded, Funded" valuenames="Unfunded, Funded" group1values="80" group2values="<?php ?get_percent = $_POST['percent']; echo$percent; ?>"]

If I replace <?php ?get_percent = $_POST['percent']; echo$percent; ?> <?php ?get_percent = $_POST['percent']; echo$percent; ?> <?php ?get_percent = $_POST['percent']; echo$percent; ?> with 20, the chart works fine. Again, I believe it is because of the ] character after the percent POST command.

I'm probably barking up the wrong tree altogether. Basically I just want the user to be able to manipulate the chart.

Help?

Thanks

Try changing: group2values="<?php ?get_percent = $_POST['percent']; echo$percent; ?>" To: group2values="<?php echo $_POST['percent']; ?>"

Basically the first part ( ?get_percent = $_POST['percent']; ) was unnecessary, and if you did need it, it should read $get_percent = $_POST['percent']; . You put a ? instead of $ .
