[Koha-devel] Disabling multiple submission on search form

[SUZUKI Arthur]

Hello,

We are facing the following problem on our installation of Koha.

Some impatient users tends to click several times on the “Go” button of the search form on OPAC.

Probably in a desperate hope that this will speed up the whole process.

However the result is quite opposite, as Zebra is then queried multiple times which increases the server cpu load, until it reach 100% and cause Denial of Service (boooh…)

 

We had the idea of disabling the “searchsubmit” button upon first click.

This is done by adding after “id=searchsubmit” in masthead.inc.

Here is a SED command to make it easier.

 

sed -i -e 's/id="searchsubmit"/id="searchsubmit" this.form.submit(); return true;"/' src/koha-tmpl/opac-tmpl/bootstrap/en/includes/masthead.inc

 

Did any of you already faced similar problems?

Any other ideas or implementation are welcome!
