html

<form action="searching.php" method="post" >     <p><label>project name</label></p>     <input name="report_name" type="text" class="form-control" placeholder="enter report name" id="report_name">     <p><label>project id</label></p>     <input name="report_id" type="text" class="form-control" placeholder="enter id report" id="report_id">     <p><label>keyword</label></p>     <input name="abstract" type="text" class="form-control" placeholder="enter keyword" id="abstract">     <p><label>student name</label></p>     <input name="student_name" type="text" class="form-control" placeholder="enter student name" id="student_name">     <p><label>advisor name</label></p>     <input name="teacher_name" type="text" class="form-control" placeholder="enter advisor name" id="teacher_name">     <br><button type="submit" name="submit" class="btn btn-primary" >submit</button>

the cause of warning: mysql_fetch_array() expects parameter 1 resource, boolean given in call mysql_connect returned false because unable connect database. docs:

returns mysql link identifier on success or false on failure.
