Definition and usage of public model classes of CI framework
This article mainly introduces the definition and usage of the CI framework (CodeIgniter) public model class. It analyzes the definition of the CI framework public model class in the form of specific examples and the related implementation skills of operating the database based on the public model class. Friends who need it can Refer to
The examples in this article describe the definition and usage of the public model classes of the CI framework (CodeIgniter). Share it with everyone for your reference, the details are as follows:
We all know that the methods of operating the database are written in the model. But under normal circumstances, a table often corresponds to at least 4 operations, which is the so-called crud. So if there are 20 tables, the corresponding model methods will reach 80. Repeated operations are obviously a physical job.
Then when operating a single table, we perform a simple encapsulation. The following is an example of the ci framework:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 |
