API Contact get fails when search string contains apostrophe
September 15, 2012, 04:35:32 am
There seems to be a bug in the Contact get API function. When you pass a parameter that contains an apostrophe (single quote) it fails to find anything.

It's easy to reproduce this on the demo environment: Just go to the API Explorer, select Contact, get, and and a parameter to the query string to search for an existing contact whose name contains an apostrophe, e.g. household_name=Sheila Smith's home. You will get no results. Now replace the apostrophe with a % and you will get the result you should have got before.

When I checked my MySQL log file I found that each apostrophe had been prefixed by three backslashes, e.g. ' becomes \\\'. Each apostrophe should be prefixed by a single backslash, not three backslashes. It seems likely that the API is unnecessarily escaping the search string twice, so ' becomes \' becomes \\\'.

This problem seems specific to the Contact API. Hopefully a fix should be fairly trivial for someone who knows the API code. Shall I create a bug report on the Issue Tracker?

I have now created an issue CRM-10857. Should I just go ahead and do that in future?

The recommended procedure is to first ask here, as you did. Not sure why we failed to respond, but anyhow, here is the page about bug reporting in CiviCRM:

Hi,

Do you have the same problem if you search using php? ie. might be a bug in the api explorer or ajax query, not in the api itself

Yes, the same problem occurs when calling the API from PHP.

I see that this issue was fixed and I've been able to confirm on my 4.3 installation that it works (i.e. I can search for names with single quotes in them from the api explorer).

I have the same or similar issue when searching a custom field that has a single quote in it - anyone with some insight into whether this is the same or a different problem?
