I'm having trouble with a dropdown menu on my form. It's supposed to show results based on what the user types in two text fields (first and last name). The weird thing is, when I check my code step by step, the SQL query looks right and includes the text from the input fields. But the dropdown stays empty, like it's not getting any results.
Here's what my code does:
1. Checks if last name is entered (shows an error if not)
2. Makes an SQL query using the last name, and first name if it's there
3. Sets the dropdown's source to this query
But when I run it, the dropdown shows nothing, even though the query seems fine. The code says there are zero items in the list.
Am I missing something obvious? Maybe there's a problem with how the dropdown connects to the data? Any tips would be great!
I’ve encountered similar issues before. One often overlooked aspect is data type mismatch between your input fields and database columns. Ensure that the data types align perfectly. Additionally, verify that your query isn’t inadvertently filtering out all results due to strict conditions. Try loosening the query criteria or using LIKE with wildcards instead of exact matches. It’s also worth checking if there are any hidden characters or whitespace in the input fields that might be affecting the search. Lastly, consider implementing error logging to capture any exceptions that might be occurring silently during the process.
Hey there! Have u checked if ur database connection is working properly? Sometimes the query looks good but the data isn’t coming thru. maybe try printing out the results of the query before setting it as the dropdown source? That could help pinpoint where things are goin wrong. What database are u using btw?
yo zack, sounds frustrating! have u double-checked the column names in ur query match exactly with ur database? even a tiny typo can mess things up. also, maybe try running the query directly in ur database tool to see if it returns results. could be a data issue rather than code problem
